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 offers high-performance polyurethane suspension bushes for Porsche’s transaxle models, including the 924, 944, and 968, produced from the late 1970s through to the mid-1990s. While these front-engined, rear-transaxle cars are renowned for their near-perfect weight distribution, many still rely on tired factory rubber. As this rubber softens and cracks with age, owners often report 944 steering vibration, instability under heavy braking, and uneven tyre wear.
Porsche Transaxle Suspension Refresh and Precision Handling
Our bushes are engineered as direct replacements for specific arms and mounting locations across the 924, 944, and 968 ranges. We ensure all applications are matched to the correct model years and specific suspension layouts, such as the later cast-alloy arms. Switching to polyurethane significantly reduces unwanted movement in the suspension joints, which sharpens steering feel and allows the chassis to hold a tighter line during spirited B-road driving or track use.
5 Technical Benefits of Polybush for Porsche Transaxle Models
Sharper Steering Response: Eliminates the “vague” off-centre feel caused by perished rubber steering rack and wishbone bushes.
Maintenance-Free Dry Fit: These components require no grease, avoiding the dirt-attracting mess and potential squeaking of lubricated alternatives.
Improved Braking Stability: Minimises castor change and “arm-smearing” under load for more consistent stopping power.
Oil and Chemical Resistance: Polyurethane is impervious to engine oil, fuel, and road grime, which frequently degrade original rubber.
Long-Term Durability: Engineered to outlast conventional rubber equivalents while maintaining their shore hardness for many years.
For any Porsche 924, 944, or 968 maintenance, replacing original rubber with Polybush is a straightforward way for workshops or experienced home mechanics to restore the car’s factory-intended precision.
