Dunlop is the sole supplier in the well-established GT Sport series which mixes GT cars of many types, united by their Dunlop tyres.

The International GT series was founded in 2006 and grew out of a national Spanish series. It runs in two classes, SGT which is based on GT2, and GTS which is based on GT3.

Ferraris and Aston Martins do battle with Porsches, Audis and even more specialised GT cars. Front engined sports cars are up against mid-engined exotics; the equation for Dunlop’s tyre engineers has a huge number of variables.
