Yokomo BD9 Mid Plate 7075 2.0mm Stiff MM Upgrade - Arrowmax AM-910017  [AM-910017]

BD9 centre plate for precision setup

The Arrowmax AM-910017 mid chassis plate is an aftermarket upgrade designed for the Yokomo BD9 MID configuration. Produced from Aium 7075 at 2.0mm thickness with a stiff MM contour, this plate is aimed at reducing centre flex and altering the car's balance to suit focused setup changes.

Use this component when you need a firmer centre section to influence roll behaviour and weight transfer on technical tracks. The plate is produced to fit the BD9 MID mounting pattern and functions as a direct replacement for the standard mid plate used in BD9 MID builds.

Fitting requires standard BD9 maintenance skills: remove the stock mid plate, position the Arrowmax plate over the existing mount points, and fasten using the original hardware. After fitting, verify electronic clearance and suspension travel, then tweak shocks and geometry incrementally to assess handling impacts.

As a tuning item, this 2.0mm stiff mid plate works best when combined with measured suspension adjustments; always re-check clearances after installation.
