Overview

The Cusco Rear Control Arm Formula Links are high-performance suspension components designed specifically for the Toyota Corolla GT-S (Trueno) from 1983 to 1987.

• Designed with adjustable mounting points, allowing for fine-tuning of suspension geometry such as camber and toe angles to optimize tire contact and grip.
• Engineered to limit factory bushing slop, which can cause vague steering and inconsistent handling, especially during aggressive driving or motorsport applications.
• Compatible with factory mounting points, making installation straightforward without the need for extensive modifications.
• Part of Cusco’s reputation for high-quality, race-inspired suspension components that enhance vehicle dynamics and driver confidence.

Performance & Handling

By replacing the factory control arms with Cusco’s Formula Links, you’ll notice a more direct and responsive steering feel, especially during high-speed cornering. The reduction in bushing slop translates into more predictable handling and improved tire contact with the road surface.
