About This Class
NASA Performance Touring is a comprehensive multi-class racing series for modified production cars, using a performance indexing system to create competitive racing across a wide range of vehicles. The class is the natural home for track-prepared street cars making the transition to competition, with 200-treadwear tire rules and moderate modification allowances keeping costs manageable. Performance Touring attracts a broad cross-section of racers and is one of NASA's most popular class groups nationally.
