Product Details

These AST Suspension 5100 Series G82 M4 coilovers fit the 2021-2026 BMW M4 Coupe RWD (G82).

This AST 5100 Series kit is a monotube, inverted coilover set that is 1-Way adjustable for rebound with one knob and adjustable for ride height. It runs the OEM top mounts, so no top mounts are included, and the rear is a non coilover setup. Springs are included, the dampers are rebuildable and the kit is made in the Netherlands.

AST lists its adjustable droplink set DLA-10-288-306 and a front quick disconnect coupling as options for this car. Cars with EDC need the delete kit, ordered separately.
