We’ve selected the material that offers the best balance of performance and comfort for your vehicle’s needs.
Our Comfort grade bushes are designed to enhance ride quality and minimise road noise, making them ideal for everyday driving. They are softer, providing maximum suspension articulation and a cushioned feel that absorbs bumps and vibrations effectively. This softer composition ensures a smoother, quieter driving experience, especially in Classic cars or Land Rovers. Comfort bushes maintain a balance between originality and ease of driving, catering to those who value a relaxed Factory-Fresh drive.
The Dynamic grade bushes offer a middle ground between Comfort and Performance. They are slightly firmer than the Comfort bushes, which improves handling and cornering response without sacrificing too much ride comfort. These bushes are ideal for drivers who enjoy a more engaging driving experience while still needing a level of comfort for daily use, whilst also being suitable for spirited driving & light track use.
Performance grade bushes are the stiffest of the three, designed for enthusiasts who demand the utmost in handling and control. They offer minimal deflection, enhancing vehicle response and stability during aggressive driving. These bushes are perfect for high-performance or track vehicles where precision and handling are critical. While they might sacrifice some ride comfort, they deliver superior driving dynamics and control, ideal for those who push their vehicle to its limits – Including Towing!
These rods are produced in 90 Shore A which allows them to be machined on a lathe.

Specifications
Polybush manufactures precision-engineered polyurethane suspension bushes for the Porsche 930, the original 911 Turbo produced between 1975 and 1989. The combination of significant turbocharged power and rear-biased weight distribution makes the condition of the suspension bushes especially important. Perished or softened rubber allows excessive movement in components such as the trailing arms, which can exaggerate the 930’s well-known “on-boost” weight transfer and rear-end squat.
Restoring Porsche 911 Turbo Handling and Geometry
Our bushes are developed as direct replacements for shared 911, 912, and 930 applications, including rear trailing arm bushes and other critical chassis mounting points. By switching to carefully specified polyurethane, you reduce unwanted flex and help the chassis maintain its intended alignment geometry. This results in far more predictable behaviour during high-speed cornering and under heavy braking, providing the stability required for such a powerful air-cooled icon.
5 Technical Advantages of Polybush for Porsche 930 Models
Controlled Weight Transfer: Minimises rear-end “squat” and instability during boost-induced acceleration.
Maintenance-Free Dry Fit: These bushes require no grease, avoiding the dirt-attracting mess and potential squeaks of lubricated alternatives.
Resilience to Perishing: Unlike traditional rubber, our polyurethane does not crack or soften with age, maintaining its shore hardness for decades.
Oil and Chemical Resistance: Impervious to engine oil, fuel, and road grime, which often degrade rubber components in the engine bay vicinity.
Improved Braking Composure: Reduces “toe-change” under load, ensuring the car tracks straight during hard deceleration.
For any Porsche 930 restoration or maintenance, replacing original rubber with Polybush is a fundamental step in returning the chassis to its factory-intended level of precision and driver connection.
