AST BMW G80-G81 M3 / G82-G83 M4 / G87 M2 2021- RWD AST 5100 Competition Series Coilovers

12 distinct rebound adjustment positions are available with the AST 5100 Competition Series Coilovers, letting you dial in your BMW M3 (G80-G81) or M4 (G82-G83) for track days or spirited street driving. These are monotube dampers, which means they have a large piston for better rebound control and won't aerate or foam up, giving you more consistent handling. The front and rear dampers use a coilover design for maximum adjustability.

This kit includes camber-adjustable front top mounts to let you fine-tune your front-end grip. Solid rear top mounts are also included. The initial spring rates and setup are based on AST's extensive development, but you can easily adjust rebound and ride height to match your specific needs. These dampers are also rebuildable at a certified AST service center.
