Corvette Z06.R GT3 Model Guide – Callaway Project C15
This article was first published at Corvette-Racing-Tripod
During the summer of 2005, a decision was made to transform selected Z06 road cars into a new breed of racer to compete in the world’s top GT3 championships. The first series to introduce this new GT3 class was the SRO and FIA’s GT3 Championship. The first export car (vin #83 Z06) was sent to Team Carsport Europe owned by well know racing pilot Toine Hezemans (owner of a C6.R in FIA GT) for evaluation. Based on their racetrack test results, Team Carsport saw instant potential in the car. Hezemans contracted Callaway Competition in conjunction with Koos Pettinga, manager at Corvette Europe, to convert the street Z06 into a Z06R GT3
Director of Callaway Competition in Germany, Ernst Woehr, jumped at the chance to work on the new Z06. The first car was stunning. After a great inaugural season in the form of 2 teams with each 3 cars, a new group of teams took interest in the car for 2007. The first customer teams to take ownership of the new car included series like: BelCar, Dutch Supercar Challenge, VLN Germany and the Italian/Spanish GT Open. With new teams, names, sponsors, and drivers, the Z06R looks even stronger for the new season.
The Z06R went on to claim wins and propelled Callaway to claim the first series title win for the car: the 2007 FIA GT3 Team Champion and the 2008 FIA GT3 Drivers Champion. For the new season, the Z06R will be seen with even more teams and new mechanical updates.
