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.
