Clutch and Flywheel for up to 500rwhp/rwtq

ferocity02 · 04-28-2018, 03:57 PM

I am contemplating a 6AT -> 6MT swap and was wondering what clutch and flywheel options people are going with for up to 500rwhp/rwtq. This will be a daily driver, so it ideally it would have a stock-like feel and engagement. I also don't want any extra NVH which I read is an issue with a single-mass flywheel. So I am leaning towards a stock-like dual-mass flywheel from Luk or other.

The car is an E90 2007 335i RWD.

I think spec stage 2 with the smfw is your best choice. Oem DMFW design is not good over 500 and can cause false misfire issues

I went with Spec Single Mass and LUK for 335is/550i, Im very satisfied, super solid performance and stock feel. But yeah it chatters at idle when im not pressing the clutch

i went with a brand new stock dmfw with a spec 2+ clutch. soft clutch pedal and very easy to drive just like stock. no missfire for me yet with my pure stage 2 turbos at 20psi on 45% ethanol

I agree with the spec stage 2. Go single mass flywheel, you can always increase idlespeed in increments until the rattle is gone.

Are there any good aftermarket dual mass flywheels? Really don't want any extra NVH. The turbo rattle is bad enough.
