The Whiteline Front Roll Center & Bump Steer Correction Kit fits the 2007-2021 Subaru WRX STI Limited (GR/GV/VA). This part is for the front of the vehicle. Trim named on the listing: Limited. Application note: Reduces roll/bump steer: essential for lowered cars. Part number KCA313. Included: 2 ball joints and 2 tie rods.
Lowering a car changes the angles of its front suspension arms. The roll center drops, and the steering tie rods no longer move in line with the control arms, which causes bump steer, where the car steers itself over bumps. This kit combines roll center correction with parts that realign the steering geometry.
Whiteline rates the install as difficult and lists about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the WRX STI: Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Adjustable Front Sway Bar Link.
