The Moton 1 Way system for the 2021+ BMW M3/M4 is a single adjustable damper. It is the same quality mono tube damper system that you already know from our line-up.

This kit also includes the 22mm shaft and 44mm piston and is perfectly useable for racing, street or track days. The 22mm shaft together with our new low friction seals are set for fast responses and good feedback during massive side load.

This is the perfect answer for racers that are not allowed to run canisters/reservoirs in their class or for people that simply love the non-remote setup.
