SuperPro Front Lower Alloy Control Arm Kit +Caster fits 15+ WRX & STI ALOY0017K

SuperPro Alloy Front Lower Control Arm Set - Additional Positive Caster

SuperPro's ALOY0017K offers a comprehensive DIY performance upgrade for your 2015-2021 Subaru WRX or WRX STI

Featuring pre-installed SuperPro bushings in the forward position of the arm and SuperPro's caster offset DuroBall bushing assembly at the rear the kit allows a bolt-on alloy arm, upgraded bushings and optimized geometry with additional caster and anti-lift geometry.

The alloy arm brings strength, rigidity and a small weight savings relative to the OE steel arms.  

The geometry upgrades offer improved tire contact patch at the front end when accelerating, cornering and braking - working the tire more effectively and efficiently to generate greater grip and traction.

The kit also includes new OEM style ball joint bosses to facilite an easier installation (the OEM peices often seize onto the OEM ball joints on the OEM arms)
