    flipm3 | E46 M3 Build Thread

    My goal with this thread is to simply document the history and progress of my own E46 M3. Everything from the day it first arrived from the dealer to the all around performer that I hope for it to be. I hope to share with all of you my own thought process on the modifications I choose for this car, as well as, proven feedback on every modification I do. This car serves as a real all year daily driver, with track days on the weekends.


    Car History
    We ordered the M3 during the summer of 2001. After being set on picking up a used E36 M3, we decided to take the plunge on an E46 M3 without ever test driving one and only seeing one in person. Several months later, the car finally arrived at our driveway in October, 2001. For the past almost near decade, the car never had an mechanical problems or mishaps. It was a true testament to BMW's amazing engineering. It has gone through countless array of weather conditions, yet still is in amazing shape. It wasn't until recently the car began to show it's age. With the car being babied and well maintained all these years, it was finally time to start replacing worn parts. The car has been left 100% stock since October 2001, and finally saw it's first modification once the OE suspension decided to call it quits. And so the modification list began to grow...

    Volk Racing CE28N Limited 08' Formula Silver

    August 2009


    A local shop helped me sell the Mag Blue CE28N's from my past G35, so I decided to use the money on CE28Ns for the M3


    Modification:
    Volk Racing CE28N's 08' Formula Silver
    19x8.5 +30mm & 19x10.5 +25mm
    Toyo Tires T1R
    255/35/19 & 275/35/19


    Pros:
    1. Lightweight for 19" wheels
    2. Forged wheels
    3. Look freaking hot!
    4. I'm Volks #1 fan boy


    Cons:
    1. Not cheap
    2. 8.5" and 30mm front was not very aggressive, nor wide
    3. I didn't have proper tire sizing for the E46 M3, since these were left over tires from my G35. Rear tires were too tall and fronts were too wide for an 8.5"

    At around 65,000 miles the OE suspension was starting to see the end of it's lifetime. It took quite a beating over it's lifetime from the nasty streets of Chicago. I started looking into many of the popular street applicable, but track focussed coilovers out there; AST 4100, GC Street/Track, TC Kline, and KW Clubsport.


    With great timing though, Stance USA just finished R&D on their E46 M3 application. I ran their GR+ Plus coilovers on my previous G35 and only had great experiences with them. In addition, they are local to where I live. I figured that I would take a leap of faith and hope that their M3 application would be as good as their Nissan ones.


    Modification:
    Stance GR+ Plus Coilovers
    Inverted Monotube Front, Standard Monotube Rear
    15 Level Single Adjustable
    Height adjustable
    Front camber pillowball plates
    Rear pillowball shock mounts
    360lbs (front) / 420lbs (rear) linear springs
    Adjustable sway bar end links
    Aluminum construction


    Pros:
    1. A ton of features for a very competitive price
    2. Linear springs
    3. Stance USA is local to Chicago, IL
    4. Options to upgrade to higher spring rates with Swift Springs
    5. Height adjustability is separated from the coilover making it easy to change heights and not mess with preload of springs.
    6. Amazing performance on the track and very streetable on the terrible streets of Chicago.


    Cons:
    1. I wish it had higher spring rates out of the box, but adjustable valving can compensate for it.
    2. With all the features they have, I wouldn't have minded if they included or added a rear spring perch plate and access to the rear shock mounts from underneath the car instead of the trunk.
    3. Not many E46 M3's using these in the market. More should definitely try them out!!

    Started to prep the car for more track usage, so I began to toy with the idea of running bucket seats. I got a great deal on a Bride Vios III, the only problem was finding a sure way of getting them mounted in the car. I called up a bunch of shops and searched every forum I could find to find a solution. Apparently, at the time it wasn't very common to through in a Bride in a BMW. Fortunately, VAC Motorsports had their floor mounts and slider that they thought were pretty confident to fit a Bride seat.


    Modifications:
    Bride Vios III: Gradiation Cloth + Carbon Kevlar shell
    Takata MPH341
    VAC Motorsports Floor Mounts
    VAC Motorsports Universal Slider
    Touge Facotry Universal Side Brackets


    Pros:
    1. EXTREMELY lightweight compared to an OE manual, no heated seat
    2. Good comfortable snug fit
    3. Absolutely no back pain, unlike using my OE seats
    4. Very easy installation
    5. I never found myself fighting my seating position throughout aggressive turns.


    Cons:
    1. I kept getting the Airbag and Seatbelt light
    2. Bride Vios III is not FIA
    3. I did not properly install the harness (did not truly mount the harness to the tunnel of the car, nor onto a roll bar/cage)

    April 2010


    I wanted to get a more track-ideal sized wheel. The Volk Racing fan that I am, I had to get 18" TE37s. I custom ordered these in November 2009 and they finally arrived April 2010! They are significantly lighter than the already featherweight CE28Ns I had previously. I also wanted to make sure I had a good aggressive looking wheel, so I ordered the lowest offset wheel offered at the time. Knowing that the car would still be seeing primarily daily driving, I decided to go with a more street focussed tire, Dunlop DZ101. In the future, I plan on picking up AD08 or NT05 for the track.


    Modifications:
    Volk Racing TE37 18x9.5 +22 White
    Dunlop DZ101 265/35/18


    Pros:
    1. VERY lightweight
    2. VERY strong
    3. I've been dying for white wheels all my life and they're truly unique
    4. The tires actually faired pretty well at Gingerman Raceway and got better as they began to heat up
    5. Treadlife is great for the tires and they're fairly affordable
    6. I love the concave face and it fits my whole JDM theme


    Cons:
    1. The tires could be stickier, but they are primarily an all-purpose type of tire
    2. The tires are naturally pretty narrow, so there is more stretch than I expected
    3. Volks are pretty pricey
    4. I ordered these WAY before the new TE37SLs were announced and they arrived literally the week Volk made the huge announcement...:lolhit:
    5. White wheels sure love brake dust, haha

    It was about time to finally change out my original brakes after tons and tons of mileage! I thought about upgrading to a BBK, but I realized that I can get the same performance with just basic rotors, lines, fluid, and eventually track-dedicated pads. My RTAB and FCAB were also just about shot and needed some good replacement. My goal with these were to go with something stronger and longer lasting that OE, but still very streetable. Finally, I decided to reinforce my rear subframe and replace the subframe bushings with new OE.


    Modifications:
    Rogue Engineering FCAB (street)
    Rogue Engineering RTAB (street)
    Rogue Engineering Clutch Stop
    CDV removed
    Turner Motorsports Rear Subframe Reinforcement
    Turner Motorsports 90mm Studs
    BMW OE Rear Subframe Bushings
    Macht Schnell 18mm Spacer (rear)
    DBA 4200 Rotors
    StopTech Stainless Steel Brake Lines
    Hawk HPS Brake Pads
    ATE Super Blue Brake Fluid


    Pros:
    1. Much better steering response and stability with the new bushings. Felt like a whole new vehicle!
    2. Shifting felt a littler smoother with the CDV removed
    3. No subframe cracks, but added sense of security with the reinforcement
    4. Braking was much more consistent with the new parts
    5. Much less brake fade compared to OE parts.
    6. The longer studs can now accomodate my rear spacers.
    7. Much less brake dust
    8. No added NVH from bushings


    Cons:
    1. Hawk HPS are pretty terrible. Poor cold bite. Poor initial bite. Poor performance all the together.
    2. I used the HPS pads at Gingerman Raceway since I couldn't order track pads. I'm sure I completely fried the pads because they just perform terribly right now.


    Touge Factory performed the whole install for everything and I highly recommend them! Their fabricator makes some of the most BEAUTIFUL welds I've ever seen. They truly are a one stop shop for all your automotive needs.

    I have been dying for a short shifter kit for quite some time, literally since the first day ever drove the car back in 2001. I was almost set on getting the Autosolutions SSK, but I had a hard time getting a hold of one. Fortunately, IND is literally 25 min away from and they are a Master Distributor of Rogue Engineering. I read a ton of reviews and couldn't find a single bad thing about them. I love how it is complete kit including the WSR. While getting the SSK done, I decided to throw in the RE Tranny Mounts to replace the worn original ones.


    Modifications:
    Rogue Engineering OCTANE Short Shifter Kit
    Rogue Engineering Transmission Mounts


    Pros:
    1. Amazing shifting feel! It is very smooth, very direct, and short!
    2. No added NVH from the stiffer transmission mounts
    3. IND did a great install and were insanely fast!


    Cons:
    1. I should have done this 9 years and 70,000 miles ago...

    I noticed that there was A LOT of drivetrain slop when driving. At the track, I had great difficult shifting in 2nd gear. I could literally feel the engine and transmission move. The transmission mounts helped stiffen the drivetrain a fair amount, but still not enough. These were clear symptoms that my engine mounts were pretty worn out. I decided to invest in the Rogue Engineering Engine Mounts since they're mocked off the Grouppe N style and lower the drivetrain about 5mm. Since my front had to be dropped a little to throw in the engine mounts, I figured that I might as well get the front subframe reinforced as well. Fortunately, local race shop, VS Motorsports, were offering some great discounts on subframe reinforcements for the winter season.


    Modifications:
    Rogue Engineering Engine Mounts
    Turner Motorsports Front Subframe Reinforcement


    Pros:
    1. Absolutely NO drivetrain slop with this engine mounts. Throttle response literally feels instantaneous. No more "Big Block V8" rocking of the engine when I tap the gas at idle.
    2. Downshifting and rev-matching is SO MUCH easier. I was absolutely shocked by the drastic difference these engine mounts made.
    3. With the stiffer engine mounts and with plans to own this car forever, the added security of the front subframe reinforcement is kind of nice. I will admit that it is a little overkill for a street driven car.


    Cons:
    1. Holy NVH Batman!! At idle, the interior of the car rocks a fair amount. With this being my daily driver, I would not enjoy the added NVH.


    The engine mounts are currently up for sale as I have decided to move back to OE Engine Mounts. Unfortunately, I have to make a compromise in performance for comfort. These engine mounts truly made a huge difference and I really loved the performance. Again, with it being my daily driver, I couldn't stand the NVH at idle.

    BACKGROUND: I have been craving to start bumping up the power of my M3 for many years now. My indecisiveness has led me towards so many different potential paths. Ultimately, I chose that in the long run, I want to build a strong reliable NA motor. Although it will be significantly more expensive than going forced induction, I feel that it suits my driving style and the personality of the car better. Despite the many and even more affordable options on the market, I chose to go with companies that I felt were very honest and offered proven power.


    SETUP CHOSEN:
    • Supersprint V2 Stepped Headers
    • Custom Performance Euro200
    • Evolve Automotive evolve-r Tune


    CONCISE REVIEWS:
    Supersprint V2 Stepped Headers
    • Known to be the best headers offered on the market
    • 100% spot on fitment
    • Beautiful welds and fabrication
    • Felt no loss in low/mid torque, but actually a gain
    • Felt a great amount of highend horsepower
    • After 3000RPM, the car felt all around stronger and quicker
    Custom Performance Euro200 Section I
    • I wanted cats to keep some backpressure to maintain low/mid torque
    • I knew they would also help mellow out the rasp and volume of the headers
    • They also help filter emissions
    • Jack truly offers a great product for an amazing price
    • His product has very clean TIG and MIG welds
    • No fitment problems at all
    Evolve Automotive Evolve-R Remote Flash
    • I chose to go with Sal@evolve due to his amazing and endless experience with tuning almost every single type of E46 M3 out there. He has such vast experience with different setups, many Alpha-N conversions, and CSLs.
    • I got a complete custom live dyno tune. So this tune is truly designed for my specific car.
    • I have quite noticeable gains in horsepower from about 4000RPM and above.
    • I feel like there is a very tangible increase in torque throughout the whole power band.
    • He offered me the capability to flash my own DME with a provided computer software and OBDII cable called the evolve-R. This offers me the ability to change up my tune if I ever need tweaking as I add new mods.
    • Eventually the evolve-R computer software will allow read/clear fault codes, data logging, and reading live data.
    • I gained a very honest and substantial bump in power. It was quite a sight to see as he slowly tuned my car throughout the day and my dyno graphs just got better and better.
    • Power was so consistent on the dyno. We did a total of 26 dyno runs and car consistently made around the same power, if not more. This clearly shows that Evolveís tune gives reliable and consistent power despite being driven hard. Truly a great asset.
    • Driving Impressions: Shift lights are SO COOL!! The car seriously pulls all the way through the powerband until the new redline at 8100RPM. I noticed some flat spots prior to the tune. These were completely rid of. The car not just continues to pull and pull. The new power is also very useable. There is much more power under pedal in the midrange. Third and fourth gears pull significantly stronger than before. I honestly was not expecting the tune to make this much of a difference. Everything is just so smooth, predictable and controllable. These were all features I need for track driving and street driving.


    OVERALL IMPRESSIONS: The combination of headers, cats, and tune has truly transformed my car. Now I feel first hand what everyone talks about on the forums when they add similar modifications. I feel like I have a new vehicle. The car is much more enjoyable to drive on the street. Nothing is overbearing, I just feel like the original great characteristics of the M3 were augmented. If I could go back, I would not change a single thing. I truly do recommend the following setup to everyone who is looking to invest in a simple setup or for those who are questioning their current one. You will not regret a single thing.


    By studying the dyno graphs on my WinPEP7, there are quite a few great things to notice. As I mentioned before, the one great thing is that power is consistent run after run. I did pull after pull within just a few minutes of one another; one would expect loss of power from heat soak and such. Not with this tune, thanks to the dyno location and Salís tune, power was very consistent pull after pull. I have many dyno graphs over 300whp!! In the graph provided, youíll notice a constant increased in power above 4500RPM. This is very noticeable on the street, especially in 3rd and 4th gear! What should be appreciated is that this is in a very useable range, but also very honest and realistic. Looking at the torque curves as well, there is an increase pretty much throughout the whole powerband, even in the low end. I was concerned with losing bottom end torque, but clearly with the headers, cats, and tune, I gained torque.


    I have driven some tuned E46 M3ís in my past. One thing that I found in other cars somewhat troublesome was the choppy or hesitant transition between partial and full throttle. This was a huge reason why I strayed away from power modifications all these years. Sal at Evolve told me that I would not experience such things with his tune. With my car driven on the track and street, I didnít want to have inconsistencies in my throttle. I did not want to have to deal with such interruptions and imbalance. On the street, I did quite a few pulls from partial throttle to full throttle back to partial, etc. The throttle is very smooth! It is really unlike anything else Iíve driven. As I mentioned, there are no flat spots in the powerband and no delays. Itís like the car and your mind are linked together. It goes when you tell it to go, no hesitation.


    I am trying to drive the car as much as I can to continue learning the changes. Overall, I am very pleased with how everything turned out. I am not sure how the carís adaptations work or if the car will continue getting stronger. All I know is that the more I drive it, the more I feel it gets stronger.


    THANKS: Thank you Sal at Evolve Automotive. You have been a true mentor and tuning guru. Your knowledge and advice is what brought my car to where it is today. Thank you spending many hours over the phone and online to get my car running the way it is now. Thank you to Jack at Custom Performance. You offered some of the best pricing on the products. Your craftsmanship with your Section I is one to greatly recognized. Thank you to the guys at TFWorks and VS Motorsports for helping with the installation. Thank you to ASpec Tuning for letting me use the dyno and internet for tuning.

    When I was last at Gingerman Raceway, I didn't have time swap my street pads for a dedicated track pad. So went through the event with my Hawk HPS brake pads. To say the least, I obliterated those pads and had to take it easy for the remainder of the event. I have been looking into getting a fairly competent and quiet street pad for awhile now. A lot of people have been recommending the StopTech Street Performance brake pads. I decided to pick up a set considering they are fairly affordable to replace my crumbled Hawks which I swore to never buy again. I also decided to flush out my nasty ATE Super Blue with some Motul RBF600. Unfortunately the ATE Super Blue loves to stay in my lines, so it may take a few flushes to completely rid of that bluish color.


    Modifications:
    StopTech Street Performance Brake Pades
    Motul RBF600


    Pros:
    1. Very quiet
    2. Low dust
    3. Good initial bite


    Cons:
    1. Still a street pad so it won't have the stopping power of track dedicated pads

    I finally received my Evolve CF Airbox!


    I won't be installing this until after my SS V1 Stepped Headers and SPipe arrive from Italy.


    Here's a quick first impression of finally seeing this firsthand. It is so damn light! It came in this huge 3f tx 2f tx 2ft box and I was getting ready to lift something heavy for some reason and literally, I almost threw it in the air. I'm curious how much weight, if any, it'll drop in the front of the car.


    The CF weave is very clean and prominent. With the gloss finish I chose, it really provides a deep 3D look. I am very happy I chose to go with gloss instead of matte. As many of you know, it is not easy laying down CF for very contour and curved shapes like this Airbox. So I was expecting to see some slight imperfections and to my surprise, it was better than expected and near OEM quality.


    I'll keep the rest of my impressions for when I have more time to really analyze the product and be able to use my dSLR to take better pics.


    Until then, enjoy some of these shots from different angles.

    I finally had a chance to get a new "baseline" dyno after replacing my pre-cat O2 sensors and EGT sensor. I also decided to utilize the dyno shop that VS Motorsports and a few M3Forum/ChiTownM members use.


    I went there with the intention of dynoing before and after the tune. Unfortunately, silly me, I forgot to re-install Windows on my MacBookPro after reformatting it with Lion OSX. So I was only able to get a dyno of just the SS V2 Stepped Headers and CPI Euro200.


    Here are the results. I am very pleased considering that my last dyno showed a gain of 17whp and 5wtq with the tune. So I figure I should be hovering around the 310whp and 245wtq range with the Evolve Stage 2 Tune on this specific dyno. The dyno operator showed me a couple other E46 M3s with different bolt ons and tunes that put down a range of 305whp to 315whp.


    Unfortunately, I will not be able to dyno the Evolve Stage 2 tune on this car considering that I will be uninstalling the headers and section 1 tomorrow to revert back to stock. I sold my SS V2 Stepped and Euro200 and promised the buyers I'd ship it out before the Holidays. Unfortunately, my SS V1 Stepped Headers and SPipe are delayed in Italy, so I will be having a couple header installs done this season. Click here to enlarge:


    Well enjoy the dynos. The next dyno will be 100% stock, then VAC Pulleys, then SS V1 Stepped/SPipe, then finally the Evolve CF Airbox/Alpha-N Tune. I am really hoping to hit the 315-320whp range. :thumbsup2:

    As you all know, I threw back on my OEM headers and section 1. I have been driving around for several days now and finally had to time to schedule some dyno time. I chose the same location, Dean's Performance, because of his great customer service, familiarity with the E46 M3, and often used dyno by other local M3 members.


    The only thing that has changed in between these and the last runs were just the headers and section 1. It must be noted that the humidity was a lot less today which may or may not skew my end results. Temperature was fairly within the same range. Again, correction factor was not that drastic.


    Upon the first dyno, I was rather shocked to see the results to say very the least. Then the results just got more and more surprising. It is said that most stock E46 M3 on the average dynojet put down 270-280whp. It looks like I am slightly above that average range. Whatever the cause is of my results, I think it's safe to say that my engine is healthy. Owning it straight from the BMW factory and making sure to do oil changes at least every 7500 miles and all the schedule Inspections/Valve Adjustments proves that despite it's 10 year old age, it is still running strong. :thumbsup2:

    Dyno graphs between 100% stock and Supersprint V2 Stepped Headers + CPI Euro200.


    I was shocked to see the difference between the two runs. I am honestly not sure how to take the results other than, what I feel on the street seems more drastic than the minute difference in numbers. What I think is most important to take from these comparisons is not necessarily numbers, but the change in the curves. The change in low end torque/power is very noticeable, as is the high end gains.


    Supersprint claims a much bigger gain in power so I am not sure what is the explanation for my lower than expected gains. It could be the change in humidity, temperature...It could be the Magnaflow cats...Who knows.


    All I know is that the SS V2 Stepped and CPI Euro200 combination made a huge difference on the street and that's what matters more to me.


    I am looking forward to seeing the comparison between the SS V2 Stepped and SS V1 Stepped which I can hopefully do in the middle of January.


    Stay tuned guys and please share your thoughts!

    My car was nearing the end of it's service countdown at around 77,000. So I decided to schedule an appointment with VS Motorsports to do the work. Although the car was schedule for an oil change according to the car's countdown, I actually decided to do a full Inspection II. This was actually my first time doing a scheduled maintenance outside of the car's extended warranty. I decided to do some of the requirements in the Inspection II simply out of "father's intuition" and I really just wanted to refresh everything and anything I could afford at the time. I also decided it would be a good time to replace some of the parts of the VANOS


    Service Done:
    Inspection I + Spark Plugs + Fuel Filter + Power Steering Flush
    Valve Adjustment
    VANOS Cam Bolts (upgraded to newer OEM version)
    VANOS Solenoid Plate
    VANOS Filter + O-Ring
    OEM Suspension (3" Lift :taserClick here to enlarge


    Review on VS Motorsports Service:
    Hands down the best speciality shop in the Chicago-land area. I am actually glad I pushed more for the Inspection II, even though VS Motorsports said I most likely needed just a scheduled oil change as indicated by my car history. Prior to this and recent oil changes, the car was 100% maintained by our local BMW dealer. My family and I have been customers of their's for literally 20 years so we gained their trust. They were the last ones who did the scheduled Inspection II at around 60,000 miles.


    When I got to VS Motorsports, everyone asked me who maintained the car prior to them. This actually got my heart beating pretty quick because I was worried they were going to tell me something catastrophic. Turns out that 9 valves were really tight on the intake side, more than what they are used to seeing. My spark plugs looked pretty nasty, even though it should have been replaced at the last Inspection II by the dealer. And my diff fluid was sludge.


    This really blew my mind because I started to really question the integrity of that dealer. Fortunately, nothing too troublesome has arisen other than I lost trust in that dealer. The wear on those fluids and spark plugs seemed rather unusual and makes me believe that the dealer did jack squat when it was under warranty.


    The car idles much better with no extraneous noises like before. Due to the crazy blizzard we had last night, I couldn't really push the car at all to determine if it's revs a little smoother. I am so glad I threw on the OEM suspension last night. It felt great to run 4x4 in 6-8" of snow, haha. The replacement of the transmission and diff fluid were much appreciate. Despite the sub-20ļF temperatures, the car shifts really smooth even as it's warming up in the morning.


    What I really wanted to emphasize in this "review" though is the service by VS Motorsports. These guys know the E46 M3 inside out. They were able to point out flaws that all previous shops have done on my car. They even inspected my subframe reinforcement and said that it could have been done a little prettier. Their customer service and how they treat you as a client is great. They really do treat you as a friend, not as a human being with a credit card. Matt, Kris, and Kenny at VS Motorsports continue to fill me in on their projects, their goals for this coming years race season, updates on how they renovate the shop. It's just fun hanging out with them. They always educate me on all these tips and tricks with the E46 and E90 M3. Good times!


    Due to my schedule, I don't have the time to work on my car as much as I'd like. So it's comforting knowing I can drop it off at a reputable shop knowing it'll come back better than how it arrived.


    So where the car stands today. Most of the preventative and schedule maintenance is taken care of. All fluids replaced, bushings have been replaced/upgraded recently. The only really next big maintenance project I have is the cooling system. I am waiting until this coming track season to see how my temps hold up, but at the looks of it now, it seems to be ok. Hopefully the crappy plastic radiator holds up for a bit as I save more pennies.

    Evolve Automotive evolve-R Stage 2 Tune Preview


    As some of you may have seen a few months ago, Evolve Automotive was searching for clients with their Stage 2 tune to BETA test a new feature. This feature allows one to be 100% catless, yet have all sensors in ready state and no SES light. I am not aware of any tuner in the world who is able to do this on the E46 M3. I emphasize that this is not simply turning off a code or a light like what most tuners do, but Evolve has developed a way to make sure all sensors are in Ready State. Truly revolutionary to me!


    http://www.m3forum.net/m3forum/showthread.php?t=386685


    I finally got a chance to contact Evolve to take advantage of this update now that I am 100% catless. It took me awhile because I was actually waiting until my car would pull an insufficiency code. After 200 miles on my SS V1 Stepped Header and V1 SPipe, I finally pulled the code!


    I figured now would be a good time to inquire about that tune update.


    I exchanged a few messages with Sal this afternoon, a few minutes later he sent me a tune update.


    It must be stressed that this feature is intended strictly for off-road use, as are all catless headers and section 1. I will be welding in new cats to comply with IL Emissions Laws soon. So for those that intend to remain 100% catless, use at your own risk.


    I haven't gotten a chance to drive much with the new tune, but so far it feels great. I will update with more driving impressions with a tuned SS V1 Stepped Header, V1 SPipe, and Evolve Stage 2 tune. I am working on scheduling a dyno session this Wednesday to do before/after dynos, so hopefully it all works out.
