Product Details

This Whiteline Front Control Arm Lower Inner Rear Bushing Comfort fits the 1998-2000 Subaru Impreza WRX RS. Whiteline part number: KCA361. You receive 2 housings, 2 washers, and 2 nuts. Placement: front. Application note: Adds 0.5 Caster & Anti Lift Comfort Option Uses 75 Duro Bushing.

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 2.5 hours. Plan on a wheel alignment afterward. To go with it on the Impreza WRX RS, see Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Front and Rear Sway Bar Kit.

Features

  • Corrosion protection: The hardware is plated to stand up to road conditions.
  • Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
  • Finish: The metal parts are powder coated for durability.
  • Install guide: Written install instructions are included with the part.
  • Material: Polyurethane construction.
