COBB Alloy Front Lower Complete Control Arm Kit w/ Standard Caster 2015-2021 WRX / 2015-2021 STI

Improve your WRX's handling to better than that of a stock STI! These Lower Control Arms are lighter weight and have stiffer bushings which improve handling characteristics.

The COBB Subaru Alloy Front Lower Control Arm, STD Alignment will increase the handling of your WRX to better than that of the STI! This is accomplished by using light-weight 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 to 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 arm 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).

Features:

• Light-weight alloy that is stronger than the original steel
• Caster increase dialed into rear bushing
• 94a durometer bushings
• Suitable for track or street use
• Improved handling
