Exedy is a Tier 1 suppoier to 11 Japanese manufactures along with Ford and GM. Works w/ OEM Dual Mass Flywheel or EXEDY Racing Lightweight Flywheel. Super low wear diaphram spring that's heat treated for long clutch life.
I've purchased 2 clutch kits prior to exedy clutch and this clutch is quality at its highest, I haven't installed yet but I'm impressed with every aspect of this part definitely will pass the word to my z owners buddies.
