Subaru Impreza is good performance car designed for rally. Because of its good performance it’s more and more used for grip racing as well. 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 knuckles / uprights bring the roll center, bumpsteer and camber curve back to normal range, provide better roll stiffness, handling and grip.
