Wheel hop in REVERSE?

Exactly right. This is why the MP suspension book tells us the pinion should be 5-7 degrees nose down in relation to the transmission output shaft. So that when the vehicle accelerates, the pinion pulls itself up and becomes aligned parallel with the transmission output shaft. Of course, for "most" street cars, technically 5-7 can be a little much, but it will still work. No matter how much you preach it, you simply cannot get people to understand and do it.
Here is a question and food for thought. I read an artical strictly for mopar pinion angle and it states mopar factory at the tranny is set at 0 degree and rear should be 3 to 4 degree down. I get that and understand. I have tranny down at 2.4 degrees and no way can i tilt the tranny up any just no tunnel room. So here is my thought. I had it with 2 degree shims on the front side and if i slipped the clutch slowly it some what worked. How about i use a set of 4 degree shims. I had 1.5 degree down using the 2 so i figure the 4 should give me about 3.5 down . What do you think????
