For 2014, after 10 years with the SCCA, C66 Racing moved to the NASA ST2 class.  The majority of NASA ST2 rules are for safety, with performance largely regulated by power-weight.  The ST2 class general rule is 8 lbs per hp.  The #66 Corvette raced in 2016 at 3200 lbs (minimum) and 400 rwhp (maximum).  Actual dyno horsepower was 395 rwhp.
