Both clutch and flywheel weren't in the car for long, less then 5000km. UAS Sports Clutch Kit looks like it is brass button based on an exedy clutch with modified pressure plate by UAS. Drove like a dream much better then the nismo clutch in my current gtr, my 300zx had very basic power so never put it up to the test but the same clutch was used on UAS's slot car at 400kw+ when they first ran their 10 sec pass. rrp $895.00 sell $400 Xtreme Chrome Molly 6kg lighten One Piece Flywheel rrp $480.00 sell $250
