Product Details
This Whiteline Front Control Arm Lower Inner Front Bushing fits the 2013-2021 Subaru WRX STI Base, Limited. The listing names the Base and Limited trims. In the box: 4 bushings and 2 tubes. Whiteline part number: W0506. The chassis code on the listing is GR/GV. Position: front.
Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired control arm bushing allows play that shows up as vague steering, a wandering feel under braking, or a clunk over bumps. Fitting a firmer one takes that slack out. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated difficult, with about 2.5 hours of work listed. An alignment is required after installation. To go with it on the WRX STI, see Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Rear Subframe Mount Bushing.
Features
- Material: Polyurethane construction.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Corrosion protection: The hardware is plated to stand up to road conditions.
- 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.
- Grease: Molybdenum disulfide grease is included to help the parts last.
