Ginetta GT4 Supercup

The regulations include sealed engines, gearboxes and differentials. This prevents expensive development of the cars and ensures that all of the cars are identical, helping to provide close racing. The Ginetta G55 Cup was introduced in 2011, the Ginetta G55 offered a 3.7 litre V6 engine and 380 BHP. Trained engineer Tomlinson himself penned the base specification for the Ginetta G50 which was produced to celebrate 50 years of Ginetta production. Home to a 3.5 litre V6 engine and 300 BHP, it has since become a successful GT4 car. ==Race weekend==
