Yokomo BD9 MID Chassis 7075 2.0mm Stiff MM by Arrowmax AM-910017  [AM-910017]

Mid chassis plate for BD9

The Arrowmax AM-910017 is an RC-scale mid chassis plate intended for use with the Yokomo BD9 platform. Built from Aium 7075 with a 2.0mm thickness and a stiff MM profile, the plate is designed to influence chassis flex and balance as part of a setup-focused upgrade.

Use this part when you want a firmer central section to change roll characteristics and weight transfer behaviour on carpet or asphalt tracks. The component is manufactured to mate with the BD9 mid chassis layout and is intended as a direct replacement for the stock mid plate in BD9 MID configurations.

Installation is straightforward for users familiar with BD9 maintenance: remove the original mid plate, align the Arrowmax plate to the existing mounting pattern, and fasten with the same mounting points used by the chassis. Verify clearance for electronics and suspension travel after fitting, and evaluate handling changes incrementally while adjusting other setup items such as shock valving or roll centers.

As a tuning part, this 2.0mm stiff mid plate is intended to be used alongside suspension and balance adjustments to refine on-track behaviour; confirm fit and re-check clearances after installation.
