Oh I see, I didn't look close enough. I've noticed the stock clutch does that often where the friction surface completely separates like that. It's an odd failure modePretty sure that's an Exedy clutch in the picture, unless you meant Exedy clutches for the 15-17 specifically.
Gotcha. You have a lot more experience and are going harder than me if you benefit from that aero you've got on there.Not so odd a failure mode…. Having the stock and Exedy clutch go in the same way.
The Organic material of both are not happy with 7k plus changes and heat.
I’m learning there a fine balance between a power clutch RXT twin for instance and a single whether organic or Cerametallic (if that’s even a word)being used for track duty.
I am going for the Cerametallic this time around. The Exedy has been good for 4 years and some 20 track weekend events. With the upgrade to material I hope the sudden failure can be avoided. Talking to Beefcake, this should be the case.
Will take a few days for shipping, flywheel skim and install, followed by the break in before I can judge the feel.
For Info.. the car is GT PP NA with mods and tune taking RWHP to 430, so not extreme, but enough for road course duty.
