Evidence, for those who need it, that GT3 isn't entirely Porsche.
For really hardcore sports car fans, there is often a serious allure to the FIA's GT3 class of racing. The cars here are based on regular cars for sale in dealerships, but at the same time have been modified just enough so as to also be serious racing machines. The BRCC (Belgian Racing Car Championships, formerly Belcar) uses these same rules, and brings such awesome cars as the Ferrari F430 GT3 that you'll see in this video to the beautiful track at Spa Francorchamps.
So although the F430 might have been replaced by the 458 in Ferrari's lineup, it certainly has some fight left on the track.
