High Quality Content by WIKIPEDIA articles! The 2007 British GT season consisted of a fourteen-round series of sports car racing in the British GT Championship. Each race meeting consisted of two one-hour endurance races, except for those at Snetterton and Silverstone, which were both single two-hour races. All of the races took place in England in 2007. Two classes raced: the more powerful GT3 and the less powerful GTC class. This was the last time the GTC class raced, before the inception of the FIA GT4 class takes over in 2008.
