Product Details
This page covers the Whiteline Rear Lower Trailing Arm Bushing for the 2015 Subaru WRX STI Launch Edition (VA). Trim named on the listing: Launch Edition. Order it as part number W63582. This part is for the rear of the vehicle. Included: 4 bushings, 2 tubes, an install guide, and grease.
Every time the wheel moves, the trailing 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. The polyurethane used here deflects much less than the original rubber under the same load.
Expect a difficult job of about 2 hours. An alignment is required after installation. To go with it on the WRX STI, see 14mm Adjustable Front Camber Bolts, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
Features
- Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Material: Made from polyurethane.
- Compliance voids: Molded voids give the bushing room to flex where it needs to.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Easy to fit: Made with the installer in mind, so it goes in without special equipment.
