Yokomo BD9 Mid-Mount Carbon Chassis Plate 2.25mm by Arrowmax AM-910018  [AM-910018]

Medius MID carbon upgrade for Yokomo BD9

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

The chassis plate is a tuning item: swapping to a thinner or thicker carbon plate changes how load is carried through suspension pick-up points and alters torsional behavior during cornering. Fit this plate when adjusting overall chassis stiffness to work with shock valving, anti-roll bar choices, or ride-height settings.

Installation uses standard BD9 mid-mount screw locations and hardware; the plate replaces the stock MID chassis and mates with existing bulkheads and side mounts. Check that your current screws and stand-offs match BD9 factory lengths before fitting, and verify alignment and clearances around the radio tray, battery bay and motor area after installation.

As a dedicated MID chassis plate, this carbon component gives a straightforward method to tune BD9 chassis stiffness for track-specific balance; pair it with measured suspension changes and validate setup updates on-track.
