Wheel spin issues

With better shocks, none of that rear susp stuff matters. The mopar bible and it's followers are still living in the 70's when it was written. Same as the Total Timing crowd and let initial fall where it may. That was in the Bible as well.

Ever seen a snubber bent down far enough to kill a driveshaft/yoke/u joint? Another reason to have it propping a door open.

Worked on cars that ran deep in the 9's, SS springs and no snubber in sight. It's a useless item on a well set up car. One of the cars went 8.70's Traction bars do the same basic thing and they are frowned upon in the mopar community. If it works, go with it. Lots of ways to skin a cat in this game.

Many, many traction issues have nothing to do with what's under the rear of the car. The front end holds back more time than most could ever expect.
