I see you're including stock clutch stuff now, you can add me if you'd like:

23k miles stage 1 including 100 octane track days, zero slipping

It sounds like there's very little if any consensus on which aftermarket clutch designs are good and which are just the same crap with different labels... this makes me glad I have not been forced to make a quick decision on a upgrade yet.

What's wrong with reusing OEM parts? As someone else mentioned, it's based off the OEM design. I don't think a few OEM bolts are the cause or affecting disc failures...

Eactly, the OEM clutches are slipping not exploding. Before any blame for an aftermarket using a design based off the OEM causing issues is doled out there is one important factor that must be addressed which isn't.

What part of the OEM design is the flaw? Is it the pressure plate? The flywheel? The friction disc?

I've said it before and I will say it again and I will continue to say it; this issue does not have a simple 1 answer solution. If the weak point was the pressure plate then people putting in a drop in disc would not be getting results. If it is the flywheel then how come there are people who are keeping the OEM flywheel and not having problems??

And as always I revert back to the same statistical fact.......OEM clutches are not all failing at the same point and the same power levels. Stock car on stock clutch fails at 9000 miles meanwhile you could have a Stage 2 car running the stock clutch for 30,000 miles.

There is clearly more than one issue going on here and it goes past bolt and spring design.

Aftermarket clutch kits are oem but not for our application.

Again referencing this thread:

Stock disc have a floating spline carrier that can compensate for axial misalignment.
This is why the springs pop out.

You said earlier that where one supplier might be faulty (ie southbend), if the other supplier uses the same design methodology (borrow from OEM) then it should be put under the same scrutiny. I think this is a key issue.

Any clutch gurus out there (Dave or Mike) care to comment on specific design features that might differentiate a particular product? For example, if it is the spline carrier that fails in Southend (pre-revision) units, how does your product do it better?

Thicker springs should stay in there better. More support around the edges perhaps.
