    Xtreme clutch for any manual n54 inc 1m

    So after my motive/spec clutch failed I had enough and started to look for alternatives.

    I've used these clutches in the past and found them extremely reliable.

    So after a few discussions with the supplier and a few delays its finally out

    It comes with 2 years warranty and very nicely priced at 2k AUD for organic

    It comes with new flywheel bolts, throw out bearing, spigot bearing and a billet alignment tool to suit either the 135 gearbox or 1m box and either 8 bolt or 6 bolt flywheel

    Comes either in organic, ceramic or kevlar.

    Its rated at around 1200nm and will be testing it out as soon as my engine is finished.

    Can we have some more info on your failure and this clutch? I presume you had the spec twin disc and that this is a twin disc as well, any idea on the differences, other than not being spec?

    Well they told be it was worn out after only 3500km, my 550i clutch has lasted more than 7000km and still going and has seen 30+ passes and a track day.

    Well this clutch is purely street and the design is definitely different, I'm not a clutch expert but this design looks far sturdier and half the price landed here in oz

    The kit comes with everything you need .

    I'll be fitting it in the new year, keep you updated.

    $1500 isn't bad but with shipping to the US it might add a bunch on top.

    Shipping shouldnt be too bad. I had a motor shipped to me from AUS for not a lot of money. Look up a freight company called TNT their pricing use to be very good.

    Shipping from oz is not that bad, it should be under 200 usd

    way cheaper than from US to OZ.

    Why is it cheaper OZ to US?

    That's not even bad. If this works well I don't see why people wouldn't swallow the shipping cost considering of all the Spec issues.

    If this works I am definitely game to try it out. I have been nursing a weak clutch for a while because I don't like the current options.

    I think @martymil is the only guy trying it out so we need to wait on his feedback.

    I will post another organic twin disc Option too :-).
    Not that "high-tec" it uses well known clutch discs and a sachs Pressure Plate- i have it in my car after the PTB Stuff didnīt work as advertised. Up to date itīs smooth as butter.

    Please do we need options but maybe start a new thread not to derail this one.

    Maybe @Sticky or someone can start a consolidated thread listing all the possible solutions and linking each one to their own thread.

    I think you would be better at it than I would.

    Great idea.

    So the new engine has gone through the initial run in procedure and all I can say the clutch is so quiet.

    The clutch is a little grabby but nothing like the spec/motiv disaster

    I have the idle set at 850rpm and its dead silent

    at 1500rpm you can barely hear the box on the hwy at cruise

    I have to put some more miles into it but the initial results look extremely promising.

    If this is all accurate then shouldn't this become the clutch of choice?

    My box is different to the 135 so I cant comment on that

    All I can do is to report on my 1m but I cant see how it will be any different

    When you look at this clutch it just reeks quality in terms of build and looks.

    It also comes with a billet alignment tool not one of those crappy plastic ones
    which makes it extremely easy and precise to align everything

    There is one thing but like every clutch that comes with a steel thrust bearing, it does make a little
    whirring noise when you engage the clutch while stationary, once driving you can't hear it.

    I'm going to contact the supplier and see if we can use the factory thrust bearing with this clutch.

    Just ticked over 700km and the clutch is awesome

    when you have the aircon on you hear a slight rattle from the box.

    Take off is like stock with a little practice and gear changes are awesome

    at 80km/h or 1800rpm there is a little cabin vibration in 6th but goes away by 90km/h but only in 6th
    every other gear is perfect and silky smooth

    Both mechanics that I use cant believe how nice it is to drive, both where very shocked.

    I promised video but its a bit hard because the camera mic cant pickup the sounds, too quiet.

    This is by far the quietest twin plate I have driven.

    I would still prefer a DMFW and a really decent clutch but at my power level it gives me misfires at high rpm levels or what some call it false knock.

    Still waiting on PTB to finally release theirs

    You dont have to wait for PTB.... Their DMFW wonīt work, trust me... Just use SMFW and be happy.
    concerning the clutch i made the same experience with "my" twin disc- for me twin disc is the future and should be in every modded car above FBO Levels.

    That's a shame about PTB

    So I tried upping the rpm to 900rpm tonight and that pretty much quietened the whole
    car down even the thrust bearing LOL

    Unbelievable what 50 rpm can do. Thank you MHD.

    Finally put some decent miles on this clutch with some aggressive
    driving, came back from a 300km trip through the twisties and she didnt miss a beat.

    The clutch is so quiet Im going to give the idea of a dmfw a rest

    You really need to experience this clutch to appriciate it of how good
    it really is.

    The clutch engagements during rapid ships are very forgiving at high
    rpm

    Took my wife for a drive and she didnt even know i had a twin plate she though i was still running the factory 550i

    The only thing i found is on take off i dont use any throttle unless needed and can get annoying learning the characteristic of this clutch

    Just take your time getting use to it
