Why failing to replace your bushings with Powerflex degrades your driving experience

The original rubber bushings fitted to your Renault Sport, Audi RS, or Volkswagen Golf are designed for comfort, but they age poorly. Over time, they soften and crack, causing steering vagueness, vibrations under braking, and uneven tire wear. Failing to equip your chassis with Powerflex bushings means accepting that your suspension will "misalign" during every hard corner, making your handling unpredictable and less secure.

The lack of rigid support for the suspension arms also leads to a loss of traction. Opting for Powerflex is not just a technical customization; it is a fundamental chassis optimization to regain that "factory-new" driving feel—and even surpass it.

Frequently Asked Questions about Powerflex

Does polyurethane generate squeaking noises?

No, provided the copper grease included with each kit is used. Correct installation with proper lubrication ensures quiet and smooth operation.

Why choose Powerflex over cheaper original parts?

The initial cost is offset by far superior durability. While original rubber degrades within a few years, Powerflex polyurethane remains stable throughout the life of the vehicle.
