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.

• Quicker steering ratio
• Rollcenter correction -50mm drop from the knuckle / upright
• Mounting points for 5x100 or 5x114.3 wheel bearings:

• Bumpsteer adjustment: Bumpsteer is adjusted via washers on the upright
• OEM wheel speed sensor: Either 1992 - 2007 or  2008 - 2013 type can be used. Hardware for installing included
• CrMo spherical Rod end used instead of OEM tie rod
• STI or WRX shocks: Adapter to fit either STI or WRX shock included
• Pre 2003 and 2015 MY steering rack adaptors
