CUSCO Rear Lateral Control Arm / Rear Camber Adjustable Pillowball – 2022+ Toyota GR86 / Subaru BRZ / 15-21 Subaru WRX

The CUSCO Rear Lower Control Arm is a direct-replacement suspension upgrade designed to improve rear-end stability, traction, and alignment adjustability for spirited street cars and dedicated track builds. Built with a pillow ball joint and lightweight aluminum construction, this arm delivers more precise suspension movement and the adjustability needed to properly dial in rear camber—especially on lowered or aggressively driven cars.

Whether you are trying to maximize grip with performance tires, improve stability in high-speed corners, or fine-tune rear alignment after lowering your car, these CUSCO lateral control arms give you the range and precision the factory arms cannot.

Key Features

• Rear Camber Adjustability: Turn-buckle style adjustment allows you to dial in rear camber for street, track, or lowered setups.
• Pillow Ball Joint: Improves precision and responsiveness by reducing bushing deflection.
• Direct OE Replacement Style: Designed to install in place of the factory rear arm.
• Lightweight Aluminum Construction: Strong, durable, and lighter than stock stamped components.
• Track & Street Proven: Helps improve traction during aggressive cornering, acceleration, and drifting.

Why We Like It

This is one of the most useful rear suspension upgrades for a lowered car. Once ride height changes, rear camber can quickly move out of the ideal range. These arms let you correct that properly while also improving precision and rear-end feedback.
