Wheel hop in REVERSE?

So much for serious answers to a serious problem. There are no burn outs. After putting it in reverse the problem occurs when trying to let clutch out. . I actually saw the wheels hop of the ground when someone else tried it. The articles i have used for every degree down the tranny is the rear must be up the same to stay parralle under normal driving. So today i removed the 2 degree up shim and replaced it with a 4 degree up. Now i have 2.7 tranny down and 4.3 up. It actually did better. I think ill machine a degree off to get it closer. I haven't pulled the rear yet to see if any issues there. Thanks to those giving serious advice.
