Broke my clutch disc
 
3 Attachment(s)
So I did this:
https://www.miataturbo.net/attachmen...ine=1435854731
https://www.miataturbo.net/attachmen...ine=1435854731
ACT part number 6224208 roughly 1 year old with 9000 miles.
Broken spring retainer on one side of the disc and a crack on the opposite side.
I'm not sure if this is a common issue or not.
Overpowered? What do some of the 350+whp guys use for clutches besides twin disc setups?

This is in a TII transmission before that question comes up.

Thanks.

Had a similar issue with a Spec disc after less than 1,000 miles.

Went to a fully "captured" spring (clutchnet disc) and it has gone 4,000 miles w/o fail.

This is why I gave up and went solid center.

Wow you popped the springs out of an ACT thats weird. Normally only see those piece of shit SPEC disks do that. I'm in the bundy solid hub club, but I wont do it with normal friction materials.

I didn't know this was a common problem.
