KW twin-adjustable suspension package for BMW 3 Series G20

Unlock serious handling gains on your G20 with KW’s premium two-way adjustable coil over suspension. This Inox stainless construction delivers precise ride height tuning plus independent bump and rebound control, giving you the stance you want and the confidence you need on B-roads, motorway runs and track days. Proven on the Nordschleife and refined on real-world roads, this setup is the go-to upgrade for sharper turn-in, flatter cornering and a composed, comfortable ride.

We install these kits on customer BMW 3 Series builds and run them on our own projects too. Feedback is consistently positive for ride quality, stability and road holding, especially on fast road use. If you want a proper suspension upgrade that works in the UK, this delivers.
