I have a stock engine 2011 Mustang GT that I run in HPDE events. I just installed a brand new Exedy Mach 500 stage 2 clutch that lasted less than one 20 minute track session before blowing up. To make matters worse I have an Auto Blip kit to rev match. The problem is one I've had before. The rivets that hold the straps on the pressure to the cover shear when down shifting. All the clutch guys design the clutches for drag racing where the straps are always in tension. When you downshift these straps are loaded in compression and have a tendency to shear the retaining rivets. I need a recommendation for a clutch that will last on the track but will still be streetable. Thnx.

 

what's wrong with an original "OEM" clutch?

 

I switched to Exedy clutch because I wanted to upgrade and add reliability. I thought an upgraded clutch from Exedy would do the job. It's rated at 500 ft lb rear wheel torque, way more than my stock motor could put out. Actually once we pulled clutch apart we found disk rivets holding outer disk to hub had sheared. Piece of exploding clutch shrapnel went through transmission bell housing. It made quite a mess. Note clutch had been broken in properly before it failed.
