“Rough” or “fast” tracks are the tracks used from cheaters the day before. There are two reasons the Street division doesn’t run these tracks. The first reason is safety. The grooves and burms in these tracks along with faster speeds increase the risk of injury and roll-over. The second reason is equipment. These tracks can be really tough on equipment. The lower profile cars that run Street get stuck, damage can occur with low hanging parts, tires get knocked off their bead and sometimes more serious equipment failures occur because of the rough tracks. If you want to run a “rough” or “fast” track in bare rubber, bring a helmet and register for Pro Street.
