Product Details

Whiteline Rear Control Arm Bushing Upper - Inner Double Offset Camber Kit is made for the 2008-2021 Subaru WRX STI (GR/GV/VA). Application note: On-car adjustable allows +/-0.75 degrees. Order it as part number KCA326. This part is for the rear of the vehicle. In the box: 8 bushings, 4 tubes, 8 bolts, 8 washers, and 4 nuts.

Every time the wheel moves, the control arm swings on its bushings. When they are soft or worn, the arm shifts under load, the alignment changes as the car moves, and steering and braking feel less precise. A stiffer bushing cuts that unwanted movement while still letting the arm pivot freely. Polyurethane resists deflection far better than the soft rubber it replaces.

Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. To go with it on the WRX STI, see Adjustable Rear Sway Bar Link, Front Control Arm Lower Inner Front Bushing, and 14mm Adjustable Front Camber Bolts.

Features

  • Finish: The metal is powder coated, which resists corrosion and wear.
  • Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
  • Install guide: Instructions for fitting are packed in the box.
  • Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
  • Bushing material: Polyurethane bushings flex far less than rubber ones.
  • Corrosion protection: The hardware is plated to stand up to road conditions.
