The Ginetta Junior Championship is a one-make racing series based in the United Kingdom. From the 2010 season teams use the Ginetta G40, having previously used the Ginetta G20. In 2026, Stéphane Ratel's SRO Motorsports Group took control of the series' management.
The cars use sealed Ford Zetec 1.8-litre engines and a sequential gearbox, and feature tubular steel chassis, fully integral FIA approved roll cages and fibreglass shells.
Meetings are usually made up of three 15-minute races. The starting grids for races one and two are determined by a 3 lap only qualifying session, each car is sent out with a 2 second gap. Each driver's fastest lap in this session sets their starting position for the first race, whilst their second fastest lap sets their starting position for race two, the finish position of race two sets the grid for race three.
