Subaru WRX & STI Alloy Arm Upgrades – ALOY0015K

SuperPro has a new Alloy arm upgrade for the 2011-2014 Subaru WRX and 2008-2014 Subaru STI Models. These arms are a complete package and include SuperPro DuroBall Bushings in the Rear and SuperPro Front Bushings and will elevate the handling of your WRX to better than that of the STI. They provide STI owners a comprehensive front end upgrade without the time or cost of installing bushings in their existing arms.

The arms are built with SuperPro increased caster ability and featuring the new “Grip Dynamics” system which combined improves grip for better handling and performance outcomes.

  • Alloy light-weight and stronger than original steel – less unsprung weight.

  • Caster Increase dialed into rear bushing.

  • SuperPro bushings for increased tire contact patch control for enhanced handling.

  • Suitable for road and track.

These arms have been designed to maximize the static caster gain over the factory arms and as always with SuperPro bushings, positive arm location ensures that dynamic alignment is maintained.

In addition, the high strength Alloy arms are more rigid and less likely to flex than the OEM steel arm, which maintains static wheel alignment settings even under the most demanding of circumstances.

These Caster Increase Arms are fitted with Uprated Ball joints and SuperPro Bushes to reduce Arm movement.
