BMW M5 Coilover Suspension Kit - Dinan ST-1 (2018–2023). This adjustable system pairs with the F90’s factory electronic shocks to deliver precise ride-height control and confident, composed handling.

Dinan replaces the springs with a more aggressive formula and adds threaded collars for easy, repeatable adjustments. A linear-rate rear spring improves predictability, while Dinan-spec progressive bump stops and helper springs preserve compliance at lowered heights. Components are machined from 6061-T6 aluminum and black anodized, and stock upper mounts are retained for quiet operation. Up to 2 in front and 2-1/8 in rear lowering is possible depending on tire clearance; Dinan recommends about 1 in front and 1-1/8 in rear to maintain ride quality. Expect notable reductions in body roll, dive, and squat. Installers should verify tire clearance at all settings.
