My car has the Summit Racing cheapie traction bars, but they are only there to prevent wheel hop, not so much for hard launch traction, although they work great, car hooks up fine. I put the snubber about 1/2 to1" down on the spring eye, and it works fine. Had them for about 4yrs and no problems.
Guess I should update this. Traction bars=BIG pieces of shit. I took them off and it transformed the car. I can handle around corners now without the ass end jacking up on one side and making handling unpredictable. I have little to no wheel hop on hard launches. My clunking and sudden spring rate change on hard bumps is gone. Slapper bars suck. That is all.
