Product Details

This page covers the Whiteline Front Upper Control Arm Bushing Kit for the 2011-2012 Mazda MX-5 Miata Special Edition. Included: 4 bushings and 4 tubes. It is listed for the NC chassis. Trim named on the listing: Special Edition. Application note: Adds 0.5 degrees Camber. Placement: front. Whiteline part number: KCA421.

Camber is the sideways lean of the wheel when viewed from the front. An offset control arm bushing places the pivot slightly off-center, which shifts the wheel's camber by a small, fixed amount without replacing the arm. On a lowered car that is often enough to bring the tires back toward an even footprint.

Expect a moderate job of about 3 hours. Plan on a wheel alignment afterward. To go with it on the MX-5 Miata, see Adjustable Rear Sway Bar Link, Adjustable Sway Bar Vehicle Link Kit, and Adjustable Front Sway Bar Link.

Features

  • Finish: The metal is powder coated, which resists corrosion and wear.
  • Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
  • Material: The part is made of polyurethane.
  • Corrosion protection: Rust protection comes from plating on the metal parts.
  • Grease: Molybdenum disulfide grease is included to help the parts last.
  • Camber adjustment: Designed to optimize camber alignment and offset the effect of body roll and tire roll in corners.
