Whiteline Rear Control Arm Bushing Upper - Inner Double Offset Camber Kit for 2010 Subaru WRX STI Special Edition (GR/GV)

Product Details

For the 2010 Subaru WRX STI Special Edition, Whiteline makes the Rear Control Arm Bushing Upper - Inner Double Offset Camber Kit. The kit contains 8 bushings, 4 tubes, 8 bolts, 8 washers, and 4 nuts. The part number is KCA326. Position: rear. Trim named on the listing: Special Edition. Whiteline's note for this fit: On-car adjustable allows +/-0.75 degrees. It is listed for the GR/GV chassis.

A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. The polyurethane used here deflects much less than the original rubber under the same load.

Installation is rated moderate, with about 3 hours of work listed. 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 Front and Rear Sway Bar Kit.
