XTD Flywheel any good?

[guitaraholic]

I'm am looking at getting another flywheel. I know JWT sells an aluminum with the holes drilled for Z33, but its $450. Also, was told that Chrome-moly is a bit stronger than aluminum.

After looking around, I saw an XTD Prolite Chrome-Moly flywheel. It weighs in at 13lbs, has a 12 month warranty. I've heard mixed reviews on the clutches (good and bad) but not much if anything on the flywheel. The XTD Prolite sells for $190, should I be suspicious? Although even the Fidanza's are only $80 more ($270).

I know to avoid the no name ones, for one,, I like my legs, and an exploding flywheel is not on the top of my things to do list. Thanks for all your opinions/reviews, they mean a lot.

honestly, for something with such horrible potential side effects like flywheels, I'd stay with the big names like Fidanza

Ive had the XTD in my car for about a year w/out problems. I'd suggest taking it to a machine shop to check balance and true.

All I can say is this- aluminum flywheel body's with steel friction surfaces are held together buy fastners or rivet's (fidanza). When the fw heats up the two metals have different heat expansion coefficients thus producing alot of shear stress on noted fastners or rivet's. This is not opinion but fact. I will never trust this design and my advise is stick with chromoloy. Exedy, Jun and XTD make kick-ass chromoly fw's. I ran the XTD prolight in my sr and loved it.
