First thing I'd check (Cause its easy) is get under and check every mount and bushing on teh engine and suspension. I had a mount fail once that messed with the drive alignment under heavy power, it would kick to the side about an inch.. Throwing the U-joint angles out the window and breaking yokes..

I checkd all mounts and iv emailed BMR they said most probably it's not the pinion angle. So far I have a BMR adustble tourq arm and stoke hight shoks and springs and rear BMR control arm and BMR subrame connectors . It's really strange why the shaft is failing m thinking next to put the car on Dyno and attached camera underneath it and see how the shaft reacts. Mean time if anyone can guide me on any thing El's I would check plz let me know . Thanks
