COBB Front Control Arm Inner Bushing Kit - Subaru WRX/STI (VA) / Impreza WRX STI (GR/GV) - Offset Alignment
This COBB kit replaces the factory front control arm inner bushings (the rear, vertically mounted bushing) on the Subaru WRX/STI (VA) and 2011-2014 Impreza WRX STI. It uses a metal and polyurethane hybrid design with high-performance bearings, and is offset to add caster. Less compliance in this bushing gives more precise steering and more predictable handling than tired factory bushings.
Note: This is the offset version, which adds caster. A standard-alignment version that keeps factory caster is also available. A wheel alignment is required after fitting. Installation by a professional is recommended.
