Whiteline offers its KCA313 Bump Steer/Roll Center Correction Kit for custom Subaru models.
Increased bump steer is one of the negative effects of lowering a vehicle from the factory ride height. The KCA313 kit was created to help eliminate bump steer through specially engineered ball joints and tie rods to bring the suspension geometry closer to OEM levels.
See the video above for a visual walk-through of how to install the kit on a Subaru WRX VA chassis.
