I've run a Fidanza alloy flywheel for years.. no problems.
The starter ring is well done, and the friction surface is fine too.
Clutch is an RPS sprung 6 puck.. 3 carbon, 3 sintered bronze.. Pressure plate looks like a stock one.. (I think RPS screwed me, but it works....)
Pressure plate is supposed to be a higher clamping force one.. And it very well might be.. it appears there is some work done to the pivot point.. but the springs are just like the stock ones I removed.. So twice the clamping force? I doubt it.
What I do not like about this clutch is the on-off nature of it. There is no slipping of this clutch for smoothness.. it engages, and that is it. Slam. you are now moving.
Try and slip it, and the thing chatters like crazy. Especially backing up slight inclines..
