I would not waste waste your money on a fidanza flywheel. There not worth 400 dollars thats for sure. I have a ram clutch in my car and I love it to death. I had a big fiasco with fidanza and they ended up giving my money back but the short time that I had it in there I wasn't very happy. I may be able to help you out on the clutch situation. Buckshot has a ram in his and he is also very happy. Plus he is pushing some HP. UR's are way over priced. the others you mentioned are good clutchs. I have heard some bad things about grizzly and UR. I may have a setup I can sell you if my other deal falls through. Kit includes clutch disc{kevlar} clutch plate, slave cylinder. Plus its about 275 dollars cheaper than UR.
