FIA GT4 European Series '2007–pr.

The GT4 European Series is a sports car championship created and organised by the Stéphane Ratel Organisation (SRO). It is an amateur championship which followed a formula similar to the FIA GT3 European Championship, which was itself derived from the FIA GT Championship which utilized the GT1 and GT2 classes. The GT4 class cars are the least powerful of the four classes, yet are equalised in order to allow driving skill to become key.
