SuperPro 2015 Subaru WRX Limited Front Lower Alloy Control Arm Kit (+Caster)

Starting with the alloy construction, these SuperPro front lower control arms for your 2015-2021 Subaru WRX are a solid upgrade over the factory steel components. The alloy material offers a good balance of strength and reduced weight, which can make a difference when you're pushing the car. They come with SuperPro's own bushings pre-installed, including a DuroBall bushing assembly at the rear that's designed to add positive caster and anti-lift geometry. This updated geometry helps keep the tire's contact patch more consistent during hard acceleration, cornering, and braking, allowing you to put more power down and maintain better control.

The kit is designed as a bolt-on replacement, aiming for a straightforward installation. SuperPro even includes new OEM-style ball joint bosses, which is a thoughtful touch because the factory ball joints can sometimes seize onto the original arms, making removal a real headache. By providing these new bosses, the installation process should be smoother, especially if you're doing it yourself. The improved geometry works the tires more effectively, leading to greater grip and a more connected feel to the road.

This kit is a comprehensive package for enhancing your WRX's front-end performance and handling. It's a well-built set that addresses both the strength and the geometry of the suspension for a noticeable improvement in how the car behaves under load.
