I had a Fidanza for about a thousand miles and it was pretty nice. Never had an ACT though. Had the CFDF/Fidanza setup, I liked it. Swapped engines so the 7bolt flywheel is now a paperweight
I'm still trying to figure out if I'm going to get a 6 bolt Fidanza and use my CFDF with that again or go ACT 2600/ACT FW. Or Competition Clutch and maybe a Fidanza?
This topics been brought up all over teh intronetz but it's always fun to hear new opinions.
