SuperPro's ALOY0018K offers a comprehensive DIY performance upgrade for your MQB Platform VW or Audi. Featuring pre-installed SuperPro bushings in the forward position of the arm and SuperPro's DuroBall bushing assembly at the rear the kit bolt on alloy arm with upgraded bushings and optimized geometry with additional caster and an increase in negative camber. 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 along with improved turn-in and mid-corner grip. SuperPro Tip: Care needs to be taken with aggressively lowered vehicles also utilizing wider wheels/tires and/or aggressive (numerically lower) wheel offsets as reducing ride height will reduce tire-to-fender liner clearance and the additional caster will move the wheel forward slightly. These factors can combine to allow the tire to rub on the fender liner at or near full steering lock such as when reversing out of a parking spot.. 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. 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.
