Is true that the 997 GT3 RS has allready enough tuning from its origins, but GMG racing has decided to make this car a little more extreme. GMG is a racing tuning specialized in the top-of-the-range sporting vehicles -like Ferrari F430.
The RS does not have any addition to its power. GMG improved its exterior by the simple presence of Champion rims with slightly raised diameter and polished edge. They did not want to kill the spirit of the car, just to make it beautiful and simple.
