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
Lower-powered versions of the Audi A3 Mk4 (8YA, 8YS) from 2020 onwards use a torsion-beam rear axle, and while these cars are still young, the mounting bushes are a genuine service and upgrade item. Owners who want the crispest possible response, or who are addressing an early rear knock, benefit from swapping the compliant factory rubber.
The rear axle mounting bushes hold the beam in place, and any give there lets the back of the car shift slightly under cornering and braking, which feels like a lack of stability and can scrub the rear tyres. Front control arm bushes affect how directly the steering responds, so keeping them precise is worth doing at the same time.
Our polyurethane bushes for the 8Y rear-axle A3 add stability and steering accuracy without an unbearable ride penalty, and they last far longer than rubber against salt and oil. Look at the 8Y multi-link range, the previous A3 8V rear axle bushes, or the wider Audi selection.
