did you lower your car and not add a camber kit... my guess (and its just a guess) is that not enough tire meat is touching the ground.. maybe from bad lowering job... id check out the camber and make it so the tire is nice and flat on the ground.. then at the track you can lower tire pressure a little.. doesn't make a HUGE differance on tires like these but may help a little.. if all else fails get drag radials.. they WILL (providing suspension is correct) solve your issues.. you are not making enough power to have traction issues with those
