Clutchmasters unsprung disc fails at 4k miles, Unsprung disc on 3SGTE w/ S54 Options

[jcbass7]

This is in my progress thread, but thought more people might want to see it/hear about it since some guys have started going with unsprung discs...


The clutch failed right at the center hub rivets. It was in the car for 6 months and only had 4,000 miles on it. Properly broken in and everything. No real hard launches, some hard pulls, but no real hard launches since FWD and crazy wheel hop.

The rep at clutchmaster's said he thinks it died since I was daily driving an unsprung clutch. I can understand the logic, the clutch was made more for weekend racing and not daily driving. Still very disappointed that it happened after only 4k miles. The whole reason I bought the unsprung was because the sprung discs fail at the springs often in this set up.. When I bought the car the clutch was broken and of course it was the springs. That clutch made it 30k so its a better option than the 4k this made it.

I called them to see if I could get it replaced since it failed so soon, they sent me an sprung stage 3 or 4 disc and resurfaced my pressure plate for 220. Not too happy to be dropping more money, but there warranty is only 90 days. lame.

I went with unsprung disc (southbend) since my 3rd gen swap, so far I have piled up just over 13,400 miles on it and shifting is still just as good. From my experience by far this is almost the longest I had a clutch not fail in my swap. The most was about 18,000miles on ACT sprung disc. I had the sprung discs previously on my 2nd gen and had some failed as little as just over a 1000miles, it was always the springs popping out. So it can go either way.
It sucks doing a clutch job, just because of the sheer amount of work involved. But this has been my experience so far with the unsprung disc, since l posted about failures of the sprung discs in the past.
