The British GT Championship is a sports car racing series based predominantly in the United Kingdom.

The series was originally created by the British Racing Drivers' Club in 1993 and, for its first two seasons, was known as the National Sports GT Challenge.

[1] The series is currently run by the SRO Motorsports Group,[2] while Pirelli began its first season as the championship's official sole tyre supplier in 2016.

[citation needed] GT3 rules include extensive balance of performance and handicap weights to make cars artificially more equal.

Regulations governing GT4 ensure the cars more closely resemble their road-going counterparts than GT3 machines, to control cost.
