Fitment Information:

1992-2007 Subaru Impreza, WRX, and STI

Features:

Subaru Impreza is a 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 uprights / knuckles bring the roll center, bumpsteer, anti-squat and camber curve back to normal range, providing better roll stiffness, handling and grip.
