Just for the record i can reccomend CFM for a decent light weight fly wheel and clutch, i got my Clutchmasters Stage 3 clutch and fly from them, along with other things, its been faultless.
Another Mod i would reccomend is fitting a vernier Cam pully to the exhaust cam and retarding the timing up to 8degrees, car has seems a hell of allot quicker after this recent mod.
