SuperPro Aluminum Control Arms (02-07 WRX, 04-07 STI)

Super-Pro has developed their own aluminum control arm kit for the GD WRX and STI, and it makes so many improvements for your cars handling, this is a must have for any WRX that will see any track time.

Super-Pro designed their own stamped aluminum control arms, which are 38% lighter than a steel arm, and these are patterned after the 2004 - 2006 STI arms that give additional caster compared to the 2007 STI, 2006-2007 WRX, and especially the 2002 - 2005 WRX with steel arms.

In addition to that improvement, they also have extra Super-Pro polyurethane bushings all ready pressed into the front of the arms for multiple different subframes.

And for a final improvement, this arm kit comes standard with the Super-Pro anti-lift kit which will also add caster to your car.

With all of the weight saved, and caster gained, this will make a significant improvement to the handling of your WRX!

Please NOTE: An alignment is required after installing these arms: these arms are Sedan width, so if you are installing them on a WRX Wagon, you may need to swap to an STI front Sway Bar, and you may have some wheel and tire rubbing that would need to be addressed.
