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
The 500c shares its running gear with the hatch, which means the same weak points. Owners often complain of a knocking rear end or floaty handling as the rear shock absorber upper bushes (OEM 51857841, 51864833) deteriorate.
The factory rubber is too soft, degrades quickly and can’t control movement properly. Polybush upgrades restore the stability the car should have had from new – perfect if you want your convertible to feel tight and controlled rather than sloppy and rattly.
Why choose Polybush over rubber?
Rubber perishes, softens and splits under load – it simply isn’t designed for long-term durability.
OEM shock absorber bushes are too soft and collapse easily, causing clunks and poor ride quality.
Polybush material is engineered to resist oil, fuel, water and road salt – it doesn’t degrade like rubber.
Once fitted, Polybush bushes restore crisp, predictable handling and will often last the life of the car.
