When Sunray DX decided to enter their team in the 24 Hours of Le Mans, they immediately ran into difficulties with Chevrolet, and probably the FIA as well (I haven't been able to find out one way or the other) because their cars were somewhat modified, and Chevrolet wanted their cars accurately represented, the rationale being that they were quite impressive while still completely stock, and therefore should be recognized as serious peformance cars. Therefore, I've also built this Le Mans version of the car, assuming a stock engine with factory racing headers, and Chevy HD wide wheels with treaded street tires on them.
