The class philosophy for Spec Corvette is to promote the equal competition of the C5 generation cars with a build that is under $20,000 not inclusive of build labor. Performance benchmarks on the car are targeted to be very similar to what 2010 SCCA T1 Corvette specifications could achieve. For example laps time at Willow Springs International raceway under 1:30. Streets of Willow Springs under 1:19 and under 1:50 at Auto Club Speedway ROval. A tight, but fast and competitively set of car specifications will allow Spec Corvette cars to easily cross over to SCCA T2 and NASA ST class racing.
