hi there i have os triple plate clutch and yes this is the third time i change the diffHey (Dubai Supra) I was wondering what clutch you were running?
The only time i have seen Ryan break he driveline parts was on a freshly preped track and he gave the car everything it has, 30+psi and lots of Spray out the hole.
I know a Carbon Clutch will help all your driveline components off the line.
also are you just buying whole new rear ends everytime you break one? or just having yours rebuilt with new gears? If it is being rebuilt you may want to check the loads and shims you person is setting them to?
