Yokomo BD9 Mid Chassis Upgrade Plate 7075 2.0mm by Arrowmax AM-910017  [AM-910017]

Mid chassis plate tailored for BD9 setups

The Arrowmax AM-910017 mid chassis plate is an aftermarket component made for the Yokomo BD9 MID platform. Constructed from Aium 7075 at a 2.0mm thickness and featuring a stiff MM profile, the plate is intended to modify centre stiffness and fine-tune chassis behaviour as part of setup work.

Install this plate when a firmer central section is required to influence roll characteristics and control weight transfer on carpet or tarmac tracks. The plate is manufactured to the BD9 MID mounting layout and serves as a direct replacement for the original mid plate.

Fitting follows standard BD9 maintenance steps: remove the factory mid plate, align the Arrowmax unit to the existing mounting pattern, and secure with the same chassis fastenings. Once installed, check for clearance around electronics and full suspension travel, then adjust shocks and geometry gradually while assessing handling changes.

This 2.0mm stiff mid plate is intended to be used with incremental suspension and balance tuning; always confirm fit and re-check clearances following installation.
