Cobb 2015-2021 Subaru WRX & STI Alloy Front Lower Control Arm (Complete) STD Alignment

The COBB Subaru Alloy Front Lower Control Arm, STD Alignment (or Offset Caster) will increase the handling of your WRX to better than that of the STI. This is accomplished by using lightweight alloy construction which yields less unsprung weight. Stiffer bushings also provide better tire contact patch control with minimal NVH and maximum service life. The difference between this unit and the offset caster LCA is the offset provided by the rear bushing assemblies. On the offset caster unit, the center of the bushing assembly is moved inboard (effective at 3 o’clock on the driver’s side and 9 o’clock on the passenger’s side when viewed from above). Doing this moves the rearward mounting position of the arms outboard, in turn sweeping the arm forward slightly which relocates the knuckle and base of the front strut forward introducing additional positive caster (~0.5° per side).
