The Renault Sports Racer group is a spec series using purpose built sports racers. These cars use a 1700 cc Renault 4 cylinder motor that puts out about 100 hp. All engines are measured on the dyno and sealed to ensure their legality and equality. These cars are extremely agile around the corners thanks to their lightweight race suspension and their and low center of gravity. They have 4 wheel disc brakes that run on 13 x 7 spec wheels with 205/60-13 DOT approved racing tires.
