Aha now the LS7 clutch problems begin. and how long exactly should I drive to break in the LS7 clutch? can I engage and disengage the clutch more than normal to wait less miles to break it in?

I broke mine in for 300 miles, not babying it but not going nuts either, per recommendation from Speed Inc.

Is this true? I was under the assumption that they were the same flywheel, inchluding the c6 zo6.

That's my car. So far I've got about 8k miles on it and it's holding really well. Of all the things I've done to the car, this clutch is one area that I don't even think of. I added the Cartek adjustable master almost immediately after install to set the pedal exactly where I want it. I don't track the car but I pound the living hell out of it....very frequently.

Feels like a stock clutch without the smell.

GTO flywheel is a different p/n. The only fw's I know which are compatible are the LS2 or the Fidanza aluminum version.

glad to see this thread helped some other people...
i talked to the guy who bought my car....and he still has no issues with the clutch...
something else i just remembered...i had a shim on the slave cylinder from the last spec 3 that was in the car.... that might have helped engagement.

Maybe it was asked already... but Whats the difference in an LS7 Clutch over any other normal aftermarket clutch? I have a Spec3+ in my car now and it has 50k miles on it and is just now slipping. Its my DD and I love the way the petal feels. What is the advantage over an LS7 clutch as I'm in the market for a new clutch.

After installing it in a buddies car because his stock one died, we noticed absolutely no change in pedal feel besides the different engagement point. And when it engages, it engages! Plus some just trust gm OEM stuff more then after market.

Mine (LS7 clutch + LS6 flywheel) is fried after 10K miles, all street driven on a stock engine with kumho crap tires. I will find out more on Thursday.

the LS7 clutch won't work with a LS6 flywheel....

LS1 and LS6 flywheels are similar, LS2 and LS7 flywheels are similar. LS1/LS6 = Gen 3, LS2/LS7 = Gen 4. All will bolt into a LSx type engine, but I was sure the LS7 clutch/pressureplate needed a LS2 style flywheel. I recall my LS1 flywheel was flat while the LS2 flywheel was indented. I didn't try linging them up, but from eyeballing it they were meant to mesh with the proper gen clutch/flywheel.
