AST BMW G80-G81 M3 / G82-G83 M4 / G87 M2 2021- RWD 5100 Street Series Coilovers (rr non coilover)

You get a set of AST 5100 Street Series Coilovers for your 2021-2023 BMW M3. These are designed to give you a better road balance for everyday use, helping you maximize grip by controlling rebound and ride height. This kit includes springs and uses your car's OEM top mounts. The front dampers are a coilover design, while the rear maintains a divorced setup like the factory setup, which makes for a more comfortable ride.

The AST 5100 Street Series uses a monotube damper design. This means a larger piston is used to control the rebound damping adjustments. Monotube dampers don't have aeration or foaming, so the valving is more responsive. You can adjust the rebound damping through 12 distinct positions, changing how the damper extends back. This lets you fine-tune the ride height and rebound to get the road balance you want. The rear springs are vehicle-specific with fixed rates. These dampers are also rebuildable at a certified AST service center.
