I have a Fidanza flywheel and just had it installed last week and I hate it. I also had a RAM Heavy Duty clutch installed with it. The thing was installed properly and it slips badly. I heard lots of horror stories about the Fidanza flywheel. RAM tells me that the slippage with the fidanza is because it was not resurfaced prior to being installed. Well a new flywheel shouldn't have to be machined. Fidanza uses such a hard compisite for the replaceable contact surface that the clutch disk just glazes over it and it never really "breaks in." You would think that resurfacing that flywheel would be easy but it's not. Since that flywheel insert has recessed holes for the screws, no machine shop will touch that. I like the feel of the Fidanza flywheel because it does have that extra HP gain but I'm not gonna risk using a different clutch and have the darn thing slip on me again. This has already cost me close to $1700 and it's going to cost more to fix the slippage. Terry Haines and others that have had this exact application tell me to just go back to the stock flywheel. Basically 1st and 2nd gear don't slip but putting it in 3rd, you'll see the tach shoot up to redline and the speedo doesn't move. YUCK!!
Has anyone out there been able to successfully use a Fidanze flywheel and if so, what clutch did you use? Was there any machining necessary for the flywheel before it was installed?
I would like to keep the Fidanza if I can but I just can't afford to keep testing out different clutches to find the one that works right.
