AST BMW G80-G81 M3 G82-G83 M4 AWD / G81 M3 X-drive 2021- 5100 STREET Coilovers (rr non coilover)

Already running an AWD setup? This AST 5100 STREET Coilover kit pairs with your 2021-2023 BMW M3 or M4. It's built to give you better road balance for everyday driving. You can control grip by adjusting how the suspension returns after hitting a bump and by changing the ride height.

This kit uses monotube dampers, which have a large piston to control rebound. This means no air gets mixed in, so the valving responds better. The front uses a coilover design, while the rear keeps the factory divorced setup. This makes for a more comfortable ride that still handles well. It comes with springs and is made to use your stock top mounts. The rear springs have fixed rates, set based on AST's development work.
