The Arrowmax AM-920050 0.5mm topdeck spacer is a focussed tuning component for the AM Medius FWD chassis. Supplied as a two-piece set, these shims allow small, repeatable changes to deck clearance without replacing core hardware.
This spacer is designated for AM Medius FWD fitment as shown in the title. Do not use it with other chassis or mounting arrangements unless instructed by your kit documentation.
Fit the spacer between the topdeck and its mounting points to alter the deck height by 0.5mm. Ensure equal placement on both sides and check the assembly on a flat surface before final tightening to avoid binding or uneven preload.
Setup notes: adding or removing the 0.5mm spacer influences chassis flex and handling in fine steps, helping you refine steering feel and weight transfer during test sessions.
