SuperPro Control Arm Kit 2002-2007 WRX / 2004-2007 STI

SuperPro's "Supaloy" aluminum WRX control arms feature the new “Grip Dynamics” system which improves grip for better handling by focusing on key alignment and dynamic handling elements. This new leaner, lighter alloy solution helps lower weight, fuel usage and running costs while improving service life and reliability.  SuperPro claims a 44% reduction in unsprung weight, better alignment geometry and improved safety with alignment enhancements.

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

• Forged aluminum alloy is light-weight and stronger than original steel – less unsprung weight.
• SuperPro Anti Lift Kit included with control arms
• Anti Lift dialled into rear bushing
• SuperPro bushings for increased tire contact patch control, minimal NV with maximum service life – better handling without a rough ride.
• Suitable for road and track

Fitment notes:

The 2007 WRX STI arms run about 1.0 degree less caster than 2004-2006 WRX STi. So 2007 STI owners will gain some caster.

These will fit 2002-2007 WRX sedan, but they run about 2.0 degrees more caster than factory stamped-steel WRX control arms. For the same reason, they will also move the wheel about an inch forward in the wheel well.

Wagon fitment is possible, but you have to run a sedan front sway bar and end links and provide additional camber adjustment, using camber bolts or camber plates.

Sold as a set of two arms -- one each right and left.

Fits all 2002-2007 Subaru WRX and STI sedan.
