FITS: 2015-2021 Subaru WRX

SuperPro's ALOY0015K offers a comprehensive DIY performance upgrade for your 2008-2014 WRX STI or 2011-2014 WRX * 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 STI style 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 facilitate an easier installation (the OEM pieces are integrated into the WRX arms and often seize onto the OEM ball joints on the OEM STI arms) * this kit will also fit a number of other Subaru models but may require other components to be swapped (sway bars, etc.) for correct fitment as well as close attention to wheel and tire sizes and wheel offsets on vehicles without the 'widebody' or blistered fenders inherent to the 08-14 STI and 11-14 WRX 

Features and Benefits

  • Lighter, stronger, faster - these words form the foundation of SuperPro's alloy control arm range. Reduce weight, increase strength, and optimize geometry for improved grip, handing and feedback
  • Factory Fit - SuperPro Alloy control arms enhance performance and handling, but also provide an quick and significant upgrade whether you DIY or have them installed by your SuperPro Authorized Dealer
