17.5 GT
The 17.5 GT class uses the same chassis as our Touring car classes. Where this class differs is with its control 17.5 turn motor and its realistic GT style bodies such as Porsche, McLaren, Aston Martin and Bugatti.
Chassis: Four-wheel drive only allowed. Chassis must have independent suspension on all four wheels. Each driven wheel must have a flexible joint, eg: dog bone/s or universal joint/s in its driveshaft. Drive train and suspension design is free from restriction. Flat Pan (1/12th and 1/10th Track Style) chassis are not allowed. The Chassis must not be shaped to gain an aerodynamic advantage. In principle the underside of the chassis must be flat and parallel to the ground along the entire length of the body-shell. Aerodynamic shaped parts (splitters/diffusers/tunnels/etc) may not be fitted to the chassis.
