Fitted to the 2011-2021 Subaru WRX STI Limited: the Whiteline Rear Toe Arm Inner Bushing. Whiteline part number: W63583. Included: 4 bushings and 2 tubes. This part is for the rear of the vehicle. Trim named on the listing: Limited. Chassis code: GR/GV.
Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired toe 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 moderate, with about 2 hours of work listed. An alignment is required after installation. Working on the same car? We also list Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Rear Subframe Mount Bushing for the WRX STI.
