Yokomo BD9 MID Chassis Carbon 2.25mm by Arrowmax AM-910018  [AM-910018]

Medius MID chassis for Yokomo BD9

This Arrowmax AM-910018 Medius MID chassis is a 2.25mm carbon replacement plate designed for the Yokomo BD9 1/10 touring car platform. It is presented as an RC-scale mid-mount chassis component intended to alter baseline stiffness and flex characteristics without changing other BD9 sub-assemblies.

The chassis plate's role is primarily tuning-oriented: changing a thinner or thicker carbon plate affects how the car transfers load through the suspension and torsional behaviour during cornering. Use this part when adjusting overall chassis stiffness to complement shock valving, anti-roll bar selection, or ride-height setups.

Installation follows standard BD9 mid-mount mounting points and hardware; the plate replaces the stock MID chassis and interfaces with existing bulkheads and side mounts. Confirm existing mounting screws and stand-offs match BD9 factory dimensions before fitting, and inspect alignment and clearances around the radio tray, battery bay, and motor area after installation.

As a dedicated MID chassis plate, this carbon component provides a predictable way to tune BD9 chassis stiffness for track-specific balance; pair it with measured suspension adjustments and validate setup changes on-track.
