Wisefab Rear Knuckles (02-07 WRX, 04-07 STI)

Subaru Impreza is good performance car designed for rally. Because of its good performance its more and more used for grip racing aswell. Lowering the car will give more grip and better handling, but then the factory designed kinematics wont 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.
