SuperPro 2015 Subaru WRX Limited Front Lower Inner Rearward DuroBall Control Arm Bushing Kit +Caster

When you're looking to tighten up the front end of your 2015-2025 Subaru WRX, especially for spirited driving or track use, the control arm bushings are a key area to address. These SuperPro DuroBall bushings replace the stock rubber components, offering a more precise connection between your suspension and chassis. They use a unique design that combines a spherical bearing with SuperPro's specialized polyurethane to give you the articulation of a bearing while still dampening road vibrations.

What's really neat about this specific kit is the 'offset' design. By introducing a small amount of additional positive caster, you'll notice your WRX tracks straighter on the highway with less effort needed to keep it centered. As you turn, this caster change also helps the outside front wheel 'camber' into the corner, putting more tire on the road for better grip. You'll also feel a bit more weight in the steering as you come off-center, which can really improve your connection to what the front tires are doing. SuperPro has been developing suspension parts in Australia for decades, and their polyurethane is known for holding up well to heat, oil, and water, all while keeping NVH (noise, vibration, and harshness) at a reasonable level.

This kit is designed to be a direct replacement for your factory inner rearward lower control arm bushings, and the caster offset is a subtle but effective change that doesn't negatively impact tire wear or comfort. It's a well-built upgrade that can make a noticeable difference in how your WRX handles.
