Should I use 2 degrees and have the rear end be up 1/2 degree or use 4 degrees and have it angled 1 1/2 degrees down relative to the transmission? This is a street car. I can't move the tailshaft of the trans upward due to clearance for the shifter (car has a narrow trans tunnel). And I can't lower the trans due to the design of the trans mount I had to fabricate. Appreciate your thoughts. Thanks
2 degree shims and a pinion snubber set to just touch the casting as far towards the transmission as you can (better mechanical advantage to resist the normal tendency for the pinion to climb the ring gear under acceleration) is one way to do it. I would use more 'pinion down' if it was a dedicated drag car.
on suspension, etc.
