Pure Stock Drag Racing tips & tricks

Marlin, this is a quote off another BB site and is a general description of wheel hop. Hopefully this gives you a little better understanding.

"Pinion angle is possibilty. I would shoot for a couple degrees down because once you get on the power, axle wind-up will bring it back to zero. That will be a trial and error process. As far as taking leafs out, I think that will hurt more than help. What's happening is the axle "wraps up" and pulls the spring to the shape of an "S" until it can't twist anymore then violently unwraps. This loading and unloading bounces the tire off the ground. Sofening the spring will make this worse. The Super Stock drag racers in the 60's used things called "spring clamps" which were basically just two pieces of flat stock drilled and tapped and bolted together around the spring leaves to keep them from separating under load effectively stiffening the spring. You might get away with just doing the right rear kind of like preloading a car with an airbag. If you REALLY want to get over your head get a book called "Circle Track Suspension" by Forbes Aird from Motorbooks International. There's more there than you want to know."
