Product Details
Owners of the 2018 Subaru WRX STI Type RA (VA) can fit the Whiteline Rear Lower Trailing Arm Bushing. You receive 4 bushings, 2 tubes, an install guide, and grease. Position: rear. The part number is W63582. Trim named on the listing: Type RA.
A trailing arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. The polyurethane used here deflects much less than the original rubber under the same load.
Installation is rated difficult, with about 2 hours of work listed. Plan on a wheel alignment afterward. Other Whiteline parts we list for the WRX STI: 14mm Adjustable Front Camber Bolts, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
Features
- Material: The part is made of polyurethane.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Install guide: Instructions for fitting are packed in the box.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
