Strongflex Polyurethane Bushings

The Strongflex hardnesses

• Sport: the base hardness, more precise than the original rubber, usable on an everyday car
• E-Sport: the harder one, for track and drift; it passes more noise into the cabin

Kits, not just bushes

Many positions are sold as a complete axle set, with every bush needed under a single code. It works out cheaper than separate parts and saves a second strip down, because you are working on the same joints anyway.

Fitting diagrams

Every product page carries the manufacturer's diagram, with the exact position of the bush on the car. Check it before you order: the same generation can have two arm variants, and the diagram separates them clearly. Pressing usually needs a hydraulic press, so count the labour in as well.

What you feel after fitting

It shows up most clearly on turn in and under hard braking: the arm no longer gives before it starts working, so the car answers the wheel earlier and more consistently. In exchange, small bumps reach the body more directly. The alternative from another manufacturer, with other hardnesses: Powerflex polyurethane bushes.
