My LS7 seems to do pretty well. I mostly play from rolls but I put down around 550rwhp when on the jug . It takes it like a champ.

I'm running a tick adjustable MC, GM slave. Only thing I am going to change is going to an aluminum flywheel.

The LS7 clutch is nothing more than a glorified stock clutch. It uses a stock pressure plate with the crappy adjusters. This makes the LS7 clutch very finicky, as it can get knocked out of adjustment very easily. It's much better to use a clutch with a pressure plate that has no adjusters. They are completely un-necessary, and jsut leave more room for error. The disc has more surface area than the stock LS1/6 disc, which is good. Then the flywheel is cast iron but even heavier than the 23-lb stocker in the LS1/6 kit.

If you want something near-stock, then you can buy a Diamond Stage 1 which uses a much stronger pressure plate (non-adjustable), with a very-similar disc to the LS7. It has better friction material with the same surface area as the LS7. This kit is just $349 shipped, and you can get your stock flywheel resurfaced for $35 or so. So under 400 bucks and stronger than the LS7.

Don't get me wrong though. There are a lot of people out the with the LS7 and it works great. But on the other hand there are also a lot of people having a lot of issues with the LS7. Based on what I've read here on the forum, and my own experience, about 80% work perfectly, and the other 20% have nothing but problems. That is way too great of a failure rate.

Do any other changes have to be made to the stock flywheel (besides resurfacing) or can you just slap it on?

Had mine in for a few months now and its seen some track time. 02 WS6 LT's, ORY, 4.10, lid, tune and works great.

I tried a comp stage 1 clutch and had it changed out twice because of the chattering. threw in the LS7 clutch/flywheel and it has a great stock feel for daily driving and holds up well at the track. I would recommend for a dd any day

What's the consensus on resurfacing the flywheel on a LS1? I have been told that you can resurface an Lt1 flywheel but not an Ls1...that it has to be new every time you do a clutch swap.
