Why choose Powerflex polyurethane bushes
Powerflex poly bushes improve your car’s road holding and chassis performance by controlling the amount of unwanted flex in the suspension, so the suspension can do its job properly. With more consistent geometry, your tyres maintain better contact with the road, improving safety and performance. Correctly formulated polyurethane is as good if not better than rubber at suppressing noise, vibration and harshness, while offering far superior longevity.
Real world results
We have fitted these on our own builds and for customers who want sharper response and confident rear-end control. Feedback is consistently positive, with noticeable gains in stability and predictability, especially during hard acceleration, fast cornering and heavy braking.
Installation and support
These inserts fit into the voids of the factory rear subframe rear bushes for a straightforward upgrade. Professional fitting recommended. For expert installation, book with Nforcd in Warwickshire. Request a quote at Sales@nforcd.com.
