I want verification that this thing is a piece of shit garbage cuntbag before I discard it. Just because it's made in China and sold via eBay doesn't automatically = garbage.

I think I may have a brand new stock LS2 flywheel in the garage. If I can find it, and it will help you, I'll send it to you for the cost of shipping just to get it the fuck out of my garage. If you're only turning 6800, I don't see the problem with the stock GM stuff.

I looked around a bit. Couldn't find a definite answer. Most reviews are showing clutch/ spring failures but no mention of flywheel issues. Maybe contact them directly..

Pretty sure grip force? don't quote me though, I'm just going off the fact that you can buy f1 racing single parts from there that f1 racing doesn't even have on there own site, and they have every brand of f1 posted on there website with grip force products as well.

I hear you on this, there is way too much "I read that they were junk..." threads on every car forum. I've run into the same problem myself on several things. It sounds like you are either going to have to take a gamble or play it safe.

Stock flywheel = near 30 lbs vs. this thing at 16. Makes a big difference in acceleration and how the engine revs. Makes shifting and rev matching easier too. I appreciate the offer, but I have a stock LS6 flywheel in my garage already... wanna trade

Yeah I read over that... most of the critiques I've found are clutch issues, but nothing to do with the flywheel. I've brought it to work today and am going to take it over to Gregory's and have them have a look at it.

I think F1 Racing is the main importer and then companies like Speed Solutions and GripForce are their larger distributors.

I'm leaning heavily toward using it... will report back after I let Gregory's look it over. Will need it resurfaced and then zero-balanced with my stock LS6 pressure plate.

1.) Al has a higher heat capacity than steel as well as a higher thermal conductivity. For this, its easier for AL to heat up, but it sheds that heat quicker. I could foresee steel getting to higher temps. Also, since there isn't an AL surface (steel replacement plate IIRC on Fidanza units), the coefficient of expansion is different ----> warping.

2.) True, but Al is weaker than steal. Do not misconstrue brittle for weak. Brittle goes to hard (strength) as ductile goes with malleable (weak). E.G. Al is 'more brittle' than most plastics.

3.) Actually, most the cheap stuff yeah. I bought an ATL fuel cell off ebay. Basically, I bought if from summit racings ebay account, for $100 cheaper than it was listed on summits website.

4.) Support the home team fucker. I just spent a solid hour at work yesterday looking for some made in USA jack stands that we need at work. 99% of the crap out there is made in china. (needed specific height). 'Murika, Fuk'ya. [http://www.usjack.com/ for those who care]

So what are you saying? AL flywheel with steel inserts is more prone to warp than a solid piece of billet chromoly?

Conducting heat across the interface between Al and steel is a problem. Operationally this isn't usually a problem except in high slip applications that crank out some serious heat.

Yurp. the delta-t is L*CE*DT, so technically the expansion would be the difference between the two. Also, since CE is usually to the order of 10^-6, you have to put a lot of heat into it to get it to matter.
