Product Details

This Whiteline Front Control Arm Lower Inner Rear Bushing MOTORSPORT fits the 1995-2000 Subaru Impreza WRX Outback. Whiteline's note for this fit: Adds +0.5 degrees Caster + Anti-Lift motorsport black option uses 95D. The part number is KCA319M. Position: front. The kit contains 2 housings, 2 washers, and 2 nuts.

Caster is the forward or backward lean of the steering axis, and more positive caster generally helps stability and steering return. This control arm bushing is made to add positive caster and alter anti-dive geometry, using a bushing swap rather than a major rebuild.

Expect a difficult job of about 2 hours. Get the car aligned once it is back on the ground. To go with it on the Impreza WRX Outback, see Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Front and Rear Sway Bar Kit.

Features

  • Corrosion protection: Plated finish keeps rust off the hardware.
  • Install guide: An install guide comes in the box.
  • Finish: The metal is powder coated, which resists corrosion and wear.
  • Anodized alloy: The alloy carries an anodized finish for durability.
  • Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
  • Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
