GA, GP and VA Subaru Impreza WRX and STI Alloy Arm Upgrade
SuperPro has a new Alloy arm upgrade for the 2011-2016 Subaru WRX and 2008-2016 WRX STI Models – it’s called the ALOY0015K.
These arms come pre-assembled and are a complete upgrade package. They include SuperPro’s unique DuroBall bushings in the rear and SuperPro front bushings. The Alloy arms are not only lighter than the standard OEM arms (reduced unsprung mass is always a good thing), they will elevate the handling of your WRX to better than that of the standard STI. For STI owners, the arms will improve the handling further still.
SuperPro’s ALOY0015K is a comprehensive front end upgrade without the time or cost of installing replacement bushings in the standard, heavier arms.
The arms are built with SuperPro’s caster-increase bushes and featuring the new “Grip Dynamics” system which improves grip for better handling and performance but won’t leave you with a harsh and uncomfortable ride like other brands of Polyurethane will do.
- Alloy light-weight and stronger than original steel – less unsprung weight.
- Caster Increase dialled into rear bushing for better steering weight, precision and directness without increasing tyre wear.
- SuperPro bushings increase tyre contact patch control for enhanced handling and reduced tyre wear.
- 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. Reduced tyre wear is another benefit.
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.
