COBB Tuning Alloy Front Lower Control Arms Subaru WRX/STI (VA)

Cobb Tuning Alloy Front Lower Control Arm Pair Caster Increase - Subaru WRX/STI 15-21

COBB Tuning has built a strong reputation for developing suspension and drivetrain components that genuinely improve how a car behaves on both road and track. These alloy front lower control arms are a direct upgrade over the factory steel units, reducing unsprung weight and improving tyre contact patch control through stiffer bushings and a purpose-designed caster offset — bringing Subaru WRX handling above stock STI levels straight out of the box.

This listing covers a pair of COBB Tuning alloy front lower control arms to suit the 2015–2021 Subaru WRX VA (FA20) and 2015–2021 Subaru STI VA (EJ25). These are the caster-increase variant, with offset rear bushing assemblies that sweep the arm forward and introduce approximately 0.5° additional positive caster per side.
