High Quality Content by WIKIPEDIA articles! The 2006 British GT season consisted of a fourteen-round series of sports car racing in the British GT Championship. The season consisted of two 2-hour enduros at Donington Park & Silverstone, with 4 other double 1 hour-race events held in England, 2 in France (held alongside the FFSA GT Championship) and 1 in Ireland. It was contested by GT2 cars, the renamed GT3 class (now GTC), and a new GT3 class conforming with new FIA regulations. This would be the last year of competition for GT2 cars, with very low grids and thus half points being awarded at most races. The following year, GT3 became the main class, with GTC supporting.
