Cusco Pillowball Front & Rear Lower Arm Bushings

2008–2010 Subaru Impreza WRX GRB / STI 2.0L Turbo

Part #: 692 464 CV

Overview

The Cusco Pillowball Front & Rear Lower Arm Bushings are high-performance suspension components designed to enhance your Subaru Impreza WRX GRB and STI models from 2008 to 2010. Engineered for enthusiasts who seek improved handling, precise steering, and increased cornering confidence, these bushings are a vital upgrade for spirited street driving, track days, or competitive racing.

By replacing the factory rubber bushings with high-precision pillow balls, these components significantly reduce suspension flex and alignment changes during aggressive driving. This results in more accurate steering response, better straight-line stability, and consistent handling characteristics, allowing you to push your vehicle to its limits with confidence.

Key Features

The Cusco Pillowball Bushings are crafted with durability and performance in mind, utilizing advanced materials and design techniques to maximize your vehicle's suspension capabilities.

• High-Precision Pillow Balls: Made from durable, high-quality materials, these pillow balls are often used in racing vehicles, providing minimal deflection and compression under load for superior control.
• Enhanced Steering Response: The pillowball design eliminates the rubber's compliance, translating to more direct and responsive steering feedback.
• Improved Cornering & Stability: Strengthening suspension joints reduces alignment changes during aggressive turns, helping maintain optimal tire contact and grip.
• Rubber Boots: Equipped with rubber boots to protect the pillow balls from dirt, debris, and moisture, ensuring long-lasting performance and minimal maintenance.
• Strengthened Suspension Joints: Reinforces the lower arm connections, reducing flex and wear over time, especially under high-stress conditions.
• Designed for Performance: Ideal for street enthusiasts, track day drivers, and racers seeking precise suspension tuning and improved vehicle dynamics.

Construction & Design

The Cusco pillowball bushings feature a robust construction with high-precision pillow balls housed within a durable, corrosion-resistant metal framework. The design minimizes deflection and maintains alignment integrity during dynamic driving conditions. Rubber boots are integrated to shield the pillow balls from dirt and contaminants, prolonging their service life. These bushings are engineered to fit seamlessly into the factory suspension geometry, ensuring straightforward installation without modifications.

Performance & Sound

By replacing the factory rubber bushings with pillow balls, you'll notice a more direct and responsive steering feel, especially during aggressive cornering and high-speed maneuvers. The increased rigidity helps improve straight-line stability and overall handling precision. While these bushings may introduce a slightly firmer ride compared to stock, they are designed to optimize performance without compromising daily drivability.

Installation & Fitment

The Cusco Pillowball Bushings are designed as bolt-on upgrades that replace the original factory components. Installation typically requires basic suspension tools and may involve removing the lower control arms. No cutting, drilling, or complex modifications are necessary. For best results, professional installation is recommended to ensure proper alignment and torque specifications are met.
