With the recent update in the e85 field my engine has been making more torque than it has the last 50k miles, ran into an srt8 last night and was all so giggly inside because I was going to destroy him, sure enough my 3.5k launch left me right alongside him the whole time as my clutch was slipping horribly through-out a 1-2-3 shift. Car smelled like absolute ass after and I feel the need to upgrade now as my factory unit seems to be useless at these power levels. Whats the best clutch to upgrade if you are seeking big power in the future but want to daily it?

I get this question a lot actually. Most people would normally say ACT Street but I dont find that to be strong enough as I've had a few guys mention their clutch after less then a year is toast. I'm not sure if its driving style or mileage.

I keep sending a lot of guys over to look at the Spec clutches. They have a lot of stages so it should fit your needs based on power.

As with any clutch and increased power you will lose some drivability and may have to sacrifice a little noise if you need to go with a light weight flywheel.

Choose a clutch based on your torque as that is what clutches are rated at.

I believe Vishnu uses a spec stage 2+ on their single turbo 650WHP+ car. Last I remember they like it.

Here is how spec clutches list their power torque rating. If you need any help let me know.

Did this clutch and flywheel combo, kind of pricey but worth every single penny.

I just did HPF stage 1. That won't be slipping anytime soon.

CM FX100 is weaker than stock clutch. They claiming +70% over stock is hilarious.

You obviously aren't very good at math....please give me an explanation as to how PLUS 70% equates to weaker than the stock clutch.

Seriously please enlighten me, use numbers and such.

Are you serious? How could your brain process that information, and then tell you that it's weaker than stock?

Evolution Racewerks is coming out with one that they will test on my car. I had my car up and transmission in pieces only to find out that the 1 series has an 8 bolt pattern and the 335i has a 6 bolt pattern. It is a sweet clutch and they should be releasing it very soon! I'll get a picture up.

FBO guys or anyone for that matter with upgraded clutches please chime in here..

What Clutch?
How many miles on new clutch?
Did you replace the flywheel or have it resurfaced?

Lets keep this based on facts and/or personal experience.

There's an extensive thread about this on the other forum.

I should have probably noted that I am currently driving a e60 535i, noobish of me to think that 335i n54 clutches will fit my car?

Since they say plus 70% they must know both figures, right?
Let CM present their math and we can laugh at their math together

Stock clutch, when new, can take 500 lb ft. Based on a small sample, guys with less than 500 have their fx100 slipping. People are "upgrading" worn out stock clutches and believe their new aftefmarket clutch holds a lot better. Yes it does, as long as it is new and is compared to a worn out stock clutch.

stock unit will take 500lb ft? didn't know this lol

Are you dumb? Seriously, what is your reading comprehension level?

They do not provide the stock numbers, they are simply stating that it will hold 70% MORE than what the stock one holds. Since the stock clutch is rated at around 350 ft-lbs (not sure where you got 500 from), lets have a small math lesson. 350 X 1.7 = 595 ft-lbs.

And you are correct, there have been 2 people that I have found that have had major failures with this clutch. Trust me, I did my research before dropping nearly 1.6k on a clutch and flywheel.

Neither of the two people I found that failed with this clutch resurfaced or replaced the flywheel. If you are changing a clutch you MUST resurface or replace the flywheel. On top of that it must be broken in properly. All the of the failures that I have seen with this clutch are user-error, which is 9 times out of 10 the case with ANY clutch replacement.

To the OP, my clutch has 3k on it now. I broke it in properly and now it holds better than the stage 4 (brand is escaping right now) I had in my track car. When installed correctly, it does a great job and is well worth the money, despite what others who have never had or installed this clutch/flywheel may think.

I'm over 500tq to the wheels and stock clutch is holding like a champ. I researched a long time before I decided to go with the spec stage 3+ with lw flywheel. I won't install it till this winter though unless the stocker fails before that.

Mine was holding right at 500 for about 2 weeks, then one time it slipped when I got on it in 6th and it was all down hill from there. 350 is about the rating is, but its def fact they hold more than thats
