The 111 and GT Sports and Saloons club championship is a circuit racing category conceived and promoted by Zwartkops. The main aim is to provide fun, competitive racing that entertains spectators at Extreme Festivals.

The 111 part of the name originates from the fact that competitors may not set a lap time quicker than 1’11″around the 2.4km long Zwartkops Raceway and are penalized if they do so.

The GT Sports & Saloons was started in 2020 to cater for those drivers who had got faster than the 1’11” allowed for the 111 category. This championship caters for cars and drivers who set times between 1’08” and 1’11” around Zwartkops Raceway.
