So I'm searching this for a while but most results the search engine returns are for N54 engines. Has anyone tried any aftermarket combo like SPEC or clutch masters?
I track the car ordinarily and wonder if the stock flywheel can last long on aggressive driving, since they're nearly $600 dollars it might make sense to buy a similarly priced SMF. Although aftermarket clutch kits are more expensive, they last longer and the sprung design will damp the vibration unlike the solid OEM clutch.
Valeo SMF conversion kit is great, but the question is where I can find replacement clutch for that kit? I asked a few sellers and Valeo and didn't get an answer.
Not trying to yield any performance gain from lightweight flywheel though, only thing I'm considering is drivability of those stage 2 clutch kits. Right now when I engage the clutch and hit the accelerator pedal too quickly, the rpm will rise a bit then drop back, makes the car jerky. I'm not sure if this is because the DMF because the CDV is already bypassed on my vehicle so when I fully release the clutch pedal the clutch should engage perfectly. This only happens if I press accelerator pedal right after releasing the clutch.

So I actually find the replacement sprung clutch for the valeo conversion kit today, it's VALEO 828533. I asked many vendor and they have no idea that such thing exist.
