• Rubber boots included to protect the pillow balls from dirt, debris, and contaminants, extending the lifespan of the components and maintaining consistent performance.
• Constructed with high-quality materials that withstand the rigors of aggressive driving and track use, providing long-lasting durability.
• Designed specifically for the Subaru Impreza WRX STi GDB chassis, ensuring a perfect fit and straightforward installation.
• Improves steering response, cornering accuracy, and overall handling dynamics, making it ideal for enthusiasts who demand precise control.
• Reduces alignment shifts during aggressive driving, helping maintain optimal tire contact and wear patterns.
• Enhances straight-line stability, especially at high speeds, contributing to safer and more confident driving.

Construction & Design

The Cusco pillowball bushings feature a robust construction utilizing high-precision pillow balls that are engineered for maximum strength and minimal deflection. The bushings are housed within a durable casing that ensures a secure fit within the suspension arms. Rubber boots are integrated into the design to shield the pillow balls from dirt, water, and other contaminants, preserving their performance over time.

The design emphasizes rigidity and responsiveness, allowing your suspension to transmit steering inputs more directly to the wheels. This setup reduces unwanted movement and enhances feedback, giving you a more connected and predictable driving experience. The components are manufactured with meticulous attention to detail, ensuring compatibility and ease of installation without the need for modifications.

Performance & Sound

By replacing the factory rubber bushings with pillowball joints, this kit significantly improves suspension responsiveness and steering precision. You can expect more immediate feedback from your steering wheel, sharper turn-in, and enhanced cornering stability. While the upgrade primarily focuses on handling and control, it also contributes to a more engaged driving feel, especially during spirited driving or track days. The increased rigidity may result in a slightly firmer ride compared to stock bushings, but this trade-off is common in performance suspension components designed for enthusiasts.

Installation & Fitment

The Cusco Pillowball Front Lower Arm Bushing Kit is designed as a bolt-on upgrade for the specified Subaru Impreza WRX STi GDB models. Installation typically involves removing the existing lower arm bushings and pressing in the pillowball units. No cutting or drilling is required, and the process can be completed with standard suspension tools. For optimal results and safety, professional installation is recommended.
