    Re: LS7 clutch kit

    If you use a C6 corvette slave cylinder, it is pretty much a bolt on.

    http://ls1tech.com/forums/cadillac-c...used-read.html

    Between these two, you should have all of your information. The first is actually a Monster clutch install, but is great for how to actually get into the clutch area. The second has more LS7 specific information.

    Edit to add: This is another great link. Follow this when installing and it can help out with avoiding clutch engagement/disengagement issues.

    I'll also add that it is a great mod to undertake. Definitely worth the time. In addition, it makes no difference if you use either the OE flywheel bolts or the ARP bolts. The ARP bolts are overkill for what the clutch can handle, but I used them because the OE bolts were going to take forever to come in and they can be reused. The OE bolts are torque-to-yield.

    Thank you all so much. The information you gave me has made up my mind. I'm ordering the kit today.

    I'm assuming that I need to drive slow to break it in and not ruin the new clutch?

    Speed has nothing to do with it, it's all about keeping clutch slip to a minimum.

    Re: LS7 clutch kit

    Everything ive ever read said to drive 200-500 normal daily driving miles. No launches. No high rpm running in lower gears. No speed shifting. Minimal clutch slippage....... Is that wrong?

    Re: LS7 clutch kit

    A proper break in is 500 miles of normal, city-like driving. No racing, no launches, no tom-foolery. You have to get plenty of heat cycles into the friction material. Otherwise you'll glaze the clutch and it won't grab well anymore.

    ^^^Not overheating and many heat cycles are the key. For the reasons above plus the pressure plate fingers need to be heat cycled. I didn't do that with one (straight to the highway for a road trip) and it lasted three months.

    You took the road trip and as a result the clutch only lasted three months? I understand it needs heat cycles but a road trip where its fully engaged for long periods of time hurt it? Im asking because you do break everything at some point.. thought maybe the clutch didnt last your turture testing

    Well, I replace it with a new LS7 disc and pressure plate assembly and broke it in the same way (minus the 1100 mile road trip) and it lasted about a year before I replaced it along with a motor swap. I installed it in a buddy's Trans Am and it's still going strong.

    Thats crazy, I never would have thought that would happen. I had planned to get mine back today and drive the 500 mile round trip to W Va this weekend. Now I'm glad that it wont be ready in time and I will driving the rental car. I would hate to go through all of this and lose the clutch again so fast.
