It is suited to formula and open-wheel cars, often on the rear axle in rally applications on tarmac or gravel and in front-engine cars; also used in NASCAR on long ovals. Together with its mix of Medium friction coefficient, Good initial bite, Mild progressive torque curve, and High heat tolerance with consistent feel, this gives RST 4 a confident, usable character.
