Topside's info is interesting. I don't run at the track (no roll bar), but I have SS springs, clamped in the front (3 clamps each side) and my pinion snubber hits the floorboard hard....hard enough that I bought one of those hemi pinion snubber reinforcement plates since I was ripping my floorboard.
In my limited experience, both pinion snubbers and slapper bars worked effectively, but I was mainly trying to prevent wheel hop.
