Whiteline Front Inner Lower Control Arm Bushing – 2008-2014 Subaru WRX / STI

Front Lower Arm Inner Bushing for the GR/GV WRX and STI
The front lower control arm inner bushing on the 2008-2014 Subaru WRX and STI (GR/GV chassis) is an inboard pivot point of the front lower arm. Whiteline’s polyurethane replacement restores precise front arm geometry on a platform where front suspension precision is central to the car’s performance character.

DETAILS

• Polyurethane front lower control arm inner bushing for GR/GV WRX/STI
• Reduces front wheel movement under cornering and braking loads
• Fits 2008-2014 Subaru WRX and STI (GR/GV chassis)
• Improves front-end precision and response
• Limited Lifetime Warranty

GR/GV Front Suspension Precision
The GR/GV WRX and STI front suspension is a MacPherson strut arrangement where front bushing quality directly affects geometry precision. The lower arm inner bushing is one of the load-bearing positions — wear here allows front wheel position variation under cornering and braking.

Anti-Lift Kit vs. Standard Bushing
The KCA334 anti-lift kit operates at the inner rear bushing position and provides geometry correction. The W0506 standard bushing is the correct replacement if anti-lift correction is not needed or has already been addressed.

Part of GR Front Refresh
The inner bushing works alongside the inner rear position and sway bar mounts for a comprehensive GR front suspension precision improvement.

The RallySport Take

Targeted front lower arm bushing replacement for GR/GV WRX and STI. Budget an afternoon for the job — bushing replacement is not complicated but does require the correct press tools and clean installation technique. Apply grease to all polyurethane-to-metal interfaces and assemble at ride height for correct bushing set. The improvement in chassis feel is immediate and the polyurethane will outlast whatever rubber is in there now.
