Vehicle Application: 92-07 Subaru Impreza WRX / STI

Subaru Impreza is good performance car designed for rally. Because of its good performance it’s more and more used for grip racing aswell. Lowering the car will give more grip and better handling, but then the factory designed kinematics won’t work as they are supposed to. Wisefab Subaru Impreza uprights / knuckles bring the roll center, bumpsteer, anti-squat and camber curve back to normal range, provide better roll stiffness, handling and grip.
