2nd LS7 clutch in a year My clutch center section blew out again this morning. It blew out back in January (after having it installed 8 months prior) and now 9 months later.
Is there any other clutch thats stronger than the LS7 and would all clutches and PP mate to the LS2 flywheel?

What exactly is "blowing out"? Do you have pictures of the damaged parts? If so please post them and I will be happy to help you better understand the cause which will certainly help in finding the best answer. Thanks,

I was just trying to narrow down whether this was a hub issue or a carrier issue. At any rate having this happen is generally indicative of a few possible causes. The first and most obvious would be a damaged or improperly installed pilot-bearing. This would be the first this I would check. This could also result from massive amounts of shock being passed through the drivetrain. Realize I am not saying you have done anything wrong; I am simply providing insight to the possible causes for this.
Is the car tracked regularly? Stock disc assemblies are relatively good at dampening shock, but when compared to an aftermarket disc they use thinner spring cage materials and weaker spring assemblies. In instances where a car is launched frequently this can occur.
Lastly, it could result from miss-shifting which would also typically damage the straps on the pressure-plate as well. What other damage has occured when this happened?
If possible give me some more info relative to your use of the car and what was happening when the damage occured.

This isn't something that I have seen occur personally but I certainly understand what you are referencing. It's odd that the hubs would sheer and then free spin. At any rate, if there isn't any damage to your plate or flywheel, other than low mileage wear you could opt for an aftermarket disc. This would keep cost down. Or you could opt for a complete kit. We offer seven different single-disc clutch options for your application. Are you planning to up the power on the car in the future? If so, let me know your goals and I will provide a recommendation. Thanks,

There a few options and thus it comes down to preference. We offer two variants for use with the LS2/3/7. One is for use with the stock flywheel (or an aftermarket flywheel with a similar design) and the other is for use with our flywheel. The OE based unit uses the stock SAC-plate as the basis for thc clutch. It will have reduced capacity over the non-SAC plate though we have sold many of these without issue (so i am unsure what you were referencing relative to issues with the use of our kits and the stock flywheel).
I would recommend the use of the non-SAC type plate. This would work with our SC75A (Aluminum) and SC75S (Steel) flywheels. As a side note there really isn't any benefit to going with the LS2 assembly especially if you are going to get a flywheel as well.
You are welcome to give me a call to discuss this further if you like. Or we can continue via posts if that works. Just let me know and I will be happy to assist you further. Thanks,

I was talking to a friend of mine who is a fellow t/a owner and he thought that my car having different gears in the rear might have something to do with the clutch disk breaking like that. I have 3.23 in the rear-end. What do you think? I wouldnt think it would though.

45k on mine and i drive the **** out of mine going through 2 sets of tires a year. I no you drive yours like a grandpa LOL maybe if ya dog ya **** maybe it will quit breaking lol . Could it have something to do with your solid motor mounts? I know they raised up you motor higher then most motors ive seen. Has to me something in the car out of line or something. Same part twice on same car and havent seen this problem for anyone else.
