The GT3 Callaway Corvette uses the factory front and rear soft bumpers. Factory headlight buckets and functional driving lights. Take a close look at the fit and finish of this car. The only non-factory body panels are the front and rear fenders (built by Callaway Competition). They are wider and lower for better grip and aerodynamics. In seven years of competition this GT3 Corvette has captured multiple team and driver championships. These GT3 Corvettes have never raced in the United States.
