British GT Championship

About the British GT Championship

For more than 25 years the British GT Championship has formed an intrinsic part of the UK’s national motorsport fabric. But, having undergone a number of changes throughout that quarter-century, it’s difficult to envisage an era more competitive than the current GT3/4 format.

It means two supercar classes, often comprising 30+ entries, compete simultaneously at Britain’s best circuits and beyond. Aston Martin, Bentley, Lamborghini and McLaren are just some of the names you’ll find on a typical British GT grid, which also features a mix of amateur and well-known professional drivers.

Races last between one and three hours. All feature a number of mandatory pitstops and driver changes.

THE CLASSES

GT3
The championship’s premier category is reserved for GT3 specification cars, which are loosely based on their road-going counterparts. GT3 has become the de facto class for customer GT racing since its emergence a little over 10 years ago, with the likes of Aston Martin, Ferrari, Lamborghini and Bentley just some of more than 15 manufacturers now competing worldwide. SRO’s renowned Balance of Performance regulations ensure each model remains competitive, regardless of the original production version’s inherent strengths and weaknesses.

GT4
Although slower than their senior class counterparts, GT4 cars still pack a real punch in terms of both performance and numbers. Two thirds of British GT’s multi-class grid is now made up of GT4s, many of which are built by the same array of manufacturers contesting GT3. While once the preserve of Ginetta and Aston Martin, GT4’s recent boom has seen the likes of Porsche, Audi, BMW and Mercedes-AMG join a rapidly expanding list of homologated marques which also include McLaren, Nissan, Lotus, KTM and Toyota.

Invitation
Occasionally a car without either GT3 or GT4 homologation is entered into British GT. In this instance it competes as an Invitation entry running outside of the general classicisation.
