Cusco Pillowball-Type Front Outer/Rear Outer/Rear Body-Side Lateral Link Bushings

2001–2007 Subaru Impreza WRX STI GDB

Part #: 660 464 LV

Overview

The Cusco Pillowball-Type Front and Rear Outer/Rear Body-Side Lateral Link Bushings are designed to enhance the handling and stability of your Subaru Impreza WRX STI GDB from 2001 to 2007. These high-performance bushings are engineered to replace the factory rubber components with precision pillow balls, providing a significant upgrade in suspension responsiveness. Ideal for enthusiasts who demand improved steering response, cornering accuracy, and straight-line stability, these bushings are a perfect addition to your vehicle’s suspension system.

Built with racing-grade materials, the Cusco pillow ball bushings help reduce alignment changes caused by suspension flex and wear. By strengthening the suspension joints that are constantly loaded during driving, they ensure your vehicle maintains optimal alignment settings for longer periods. This results in more predictable handling characteristics, especially during spirited driving or track use, where precise suspension behavior is critical.

Key Features

The Cusco pillow ball bushings incorporate several advanced features that set them apart from standard rubber bushings:

• High-precision pillow balls crafted from durable materials, often used in racing vehicles, to withstand aggressive driving conditions.
• Elimination of compression and deflection typical of rubber bushings, allowing the suspension to fully demonstrate its original performance capabilities.
• Rubber boots included to protect the pillow balls from dirt, debris, and moisture, ensuring long-lasting performance and minimal maintenance.
• Designed specifically for the front outer and rear outer/ rear body-side lateral links, providing targeted reinforcement where it matters most for handling.
• Constructed with high-quality materials that resist wear and deformation, maintaining optimal suspension geometry over time.
• Improves steering response and enhances the vehicle's overall cornering precision, making it ideal for both street and track use.
• Engineered to reduce suspension flex, helping to maintain proper wheel alignment and tire contact patch during aggressive maneuvers.
• Manufactured by Cusco, a trusted name in performance suspension components, ensuring quality and reliability.

Construction & Design

The Cusco pillow ball bushings feature a robust construction that combines high-precision pillow balls with a protective rubber boot. The pillow balls are machined from high-strength materials, providing a firm and stable connection that minimizes unwanted movement and flex. The rubber boots serve to shield the pillow balls from dirt, mud, and moisture, which can cause premature wear or corrosion. This design ensures that the bushings maintain their performance characteristics over an extended period, even under demanding driving conditions.

The bushings are designed to replace the factory rubber components seamlessly, offering a direct bolt-on upgrade. Their compact and precise design ensures a perfect fit within the existing suspension geometry, allowing for straightforward installation without modifications. The use of high-quality materials and meticulous manufacturing processes guarantees durability, consistent performance, and long service life.

Performance & Handling

By replacing the factory rubber bushings with Cusco pillow ball-type bushings, you will notice a marked improvement in steering response and cornering stability. The elimination of compliance in the suspension joints results in more direct feedback from the road, giving you greater confidence and control during spirited driving or competitive events. The enhanced rigidity helps maintain proper suspension geometry, which can lead to improved tire grip and more predictable handling characteristics.

While these bushings are designed for performance, they also contribute to a more engaging driving experience by providing sharper turn-in and reduced body roll. The increased precision makes them suitable for enthusiasts who want to push their Subaru Impreza WRX STI GDB to its handling limits, whether on the street or the track.

Installation & Fitment

The Cusco pillow ball bushings are designed as direct replacements for the factory components, making installation straightforward for those with basic suspension knowledge. No cutting, drilling, or complex modifications are required. It is recommended to follow proper suspension alignment procedures after installation to maximize the benefits of these upgraded bushings. Basic tools and a lift or jack stand setup will suffice for a proper installation.
