I'll do some more research, and see what I can stir up. The problem with the WaveTrac on a road course, according to Justin, is that when cornering hard, and unloading the outside tire, the WaveTrac couldn't transfer the torque to the inside tire and adequately reduce the torque to the outside tire to minimize wheel spin. When I have watched the few videos of Crossfires on road course, you can hear them losing traction on the tight corners. See, you straightline guys have it easy:-))
Thanks for your feedback! Have fun!
