How it feels on the road

On British B-roads the chassis stays planted, steering response is crisper and the car flows with the surface. Dial in a sensible drop to close the arch gap, enjoy a supple daily ride in the softest map, then switch to the firmer presets for weekend blasts. Our customers consistently praise the improvement in grip, stability and confidence, and we have fitted this setup ourselves with excellent results.
