What Do The Different Grades Mean?

When There’s No Option Available:

We’ve selected the material that offers the best balance of performance and comfort for your vehicle’s needs.

Comfort (Blue 65A):

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.

Dynamic (Orange 75A):

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 (RED 85A):

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!

Machinable Material:

These rods are produced in 90 Shore A which allows them to be machined on a lathe.

Specifications

Seat Leon Mk 1 Cupra 4 bushes are a different proposition to the front wheel drive cars, because the 1M1 is the only Leon of its generation with drive going to the back. That four wheel drive system brings a Haldex coupling, a rear differential and a rear subframe, and every one of those assemblies is bolted to the shell through rubber that has now had twenty years of torque working against it.

Those mounts are where to start. The rear subframe bush, the rear differential cradle Haldex mounting bush and the rear gearbox support bush together stop the driveline twisting away from the body under power. When they sag, the car feels like it takes up drive a fraction after you ask it to. Behind them, the rear track arm inner and outer bushes and the trailing arm to chassis bush set rear toe, which on a four wheel drive car is what decides whether it tightens or runs wide when you get back on the throttle.

The front uses the cast lower arm with a 45mm front bush. See the Cupra R, the standard Leon Mk 1, or the Seat range.
