Real-world comfort with confident handling

If your factory setup or previous lowering springs feel crashy or unsettled, this is the comfort upgrade you have been looking for. Reduce float and pitch, calm down bouncy responses and tighten directional stability while keeping daily usability intact. Wind on a few clicks of rebound for sharper feedback on a smooth A-road or back it off for maximum plushness on rougher urban surfaces.

Personalised rebound control in 16 clicks

Dial in your preferred feel quickly and consistently. Add firmness for bigger wheel and tyre packages or spirited road use. Go softer for long-distance comfort and poor surfaces. The balance remains predictable so adjustments are intuitive and easy to repeat.

Neat drop, everyday practicality

Achieve an OEM-plus stance with functional ground clearance. Unlike fixed springs, this kit lets you set the height where you want it within a TÜV-tested window. Front 15 to 40 mm and rear 20 to 45 mm gives you flexibility for daily life, speed humps and car park ramps.

Built to last

KW’s inox-line construction shrugs off winter salt and wet conditions. The precision threads and composite collars stay usable season after season, so height changes and corner-weighting remain straightforward down the line.
