How it drives

Turn the rebound up for tighter body control, faster direction changes and confidence at speed, or wind it back for a more compliant ride on poor roads and winter tyres. We run KW on our own cars and have installed many V2 kits for customers. Feedback is consistently positive: superb road manners, better stability, and a premium OE-plus feel that works every day.
