Real-world results you can feel

We have installed and driven on these KW stainless coil-overs on multiple E93 builds. The feedback is consistent: flatter cornering, smoother control over rough surfaces and a stance that transforms the look of the car. Owners praise the confidence it brings on B-roads while remaining perfectly liveable for commuting and long trips.

Height adjustment and construction details

Achieve the exact ride height you want within the tested range. The front uses a robust composite height adjuster. Where the rear uses a separate spring and damper layout, the supplied adjuster sits above or below the spring as required. The dirt resistant thread design keeps adjustments smooth even after years of use in all weathers.
