Hi

I recently ran out of clutch in my BRZ after 6 months of ownership (yea well... I also ran out of 3 rear tires sets so it may be somehow related). Anyhow, car is still on warranty so I'm still servicing it at Subaru. I asked them about STI clutch and guys at subaru told me it's plain scam tbh and if they were to be completely honest they'd much rather recommend me getting Stage 2 Xtreme clutch for my type of driving and said that they'll be more than happy to install it instead as part of next service interval so that I shouldn't have any warranty issues etc.

So I googled a bit and indeed those clutches seem to be available here and I narrowed down my choice to 3 options. Mostly those two:
KSU23512-1B and KSU23512-1C

Both are Stage 2 with the same components but one is cushioned ceramic and another one is sprung ceramic. What's difference? Also should I get one with flywheel or one without? Price difference between KSU23012-1B (without flywheel) seems to be like 250$ so not much.
