It the last few days, many NMRA Renegade and NMCA Xtreme Street racers have approached the NMRA/NMCA Tech department regarding the crossover from Ultra Street into those two categories. For the last few years, the two racing series have been moving toward the goal of being aligned with Ultra Street to make it easier for racers to cross back and forth. Changes were made to the Ultra Street rules following the NMRA/NMCA rules release in 2020, unbeknownst to the tech officials until it was recently pointed out. The rules committee felt it was best to make the necessary rules adjustments to maintain the class crossover capability in 2020. To check out the latest rules updates, click HERE. The NMCA technical department, at its discretion, reserves the right to change, modify, add, or eliminate specific class rules at any time.
