Putting a LS1 crate motor in my father's Panoz. Have a few options on clutches, don't need anything fancy as it'll only make around 330 rwhp. I have one of these (http://www.allreplacement.com/product/3386) sitting on my work bench right now for $0.00. It's only 2lbs heavier than a Fidanza aluminum unit. I also have an old 2001 Z06 stock pressure plate and disc from an old car.

I was thinking of using them together for a grand total of $0.00, but I'd rather spend the money and do it right/once vs. installing crap.



Thoughts? Internet browsing says:

1. Chromoly is far more prone to warp when heated.

2. Chromoly is more brittle than billet steel or aluminum.

3. Everything off of eBay is 100% garbage.

4. All you guys are fools for buying expensive stuff when it's made in China anyway and I've had no problems with mine.

Haven't used it, but I believe F1 products are offered for sale by reputable BMW parts source such as Turner and bimmerworld.

SFI Rated, light weight without having to having an aluminum center insert that I would imagine is more prone to warping though I have never had trouble with mine.

Saving rotating mass on the car will help it up through the rpms. It seems well thought out with the drilled holes around the perimeter to save weight at the outer most edges where it matters most.

No one can make blanket statements about ebay: good, bad, or otherwise you must know your product, do the research, make an informed decision, just like you were talking to a "guy" at the local shop.

No firsthand experience, but when i was on the bmw forums, a lot of people used those flywheels.

Any stories of component failure or warping floating around?
