BMW E90 E92 xDrive AWD Suspension Upgrade by ST Suspension, Part No. 13220048

Unlock sharper handling, a purposeful stance and confidence on every British B-road with the ST X coil-over suspension set from ST Suspension, engineered by KW Automotive. This complete ride height adjustable shock and spring package transforms all-wheel-drive 3 Series E90 saloon and E92 coupé models with precise control, everyday comfort and a clean, even drop that looks right and drives better.

We run these on our own E9x xDrive builds and our customers love the result. Expect crisper turn-in, reduced body roll, less squat and dive, and a planted feel on motorway runs and spirited drives alike. It is a direct-fit, bolt-on solution designed for fast road use, engineered for long-term reliability in UK weather.
