Wouldn't it be fair to say that if you have wheel hop and put on a pair of SS springs it will go away. However if you decide to go for a skinnier tire it may come right back? Also I am not interested in sticking my head under the car during a launch to determine my pinion angle either. If it was off I would have to experiment with shims anyway. I let the snubber stop it when the driveshaft and yoke are aligned. By far the easiest way.
