BMW M4 Coilover Suspension Kit - Dinan - Adjustable, Dinan ST1 - Black - 21-26. A height-adjustable spring system for 2021-2026 M4 models that sharpens response while retaining the factory electronic dampers.
Dinan keeps the OEM adaptive shocks and installs a tuned spring package: firmer fronts for control and a softer, dual-rate rear for predictability and grip. Threaded collars let you set ride height, with progressive bump stops and included packers to preserve ride quality and fine-tune feel. For the M4, a drop of about 3/4 inch front and rear is recommended; up to roughly 1-1/8 inch front and 2-1/4 inch rear is possible, but always verify tire clearance.
