Yokomo BD9 Flex Tuning Plate Magnesium - Arrowmax AM-900005  [AM-900005]

Overview of Arrowmax AM-900005

The Arrowmax AM-900005 is an RC-scale upgrade made for the Yokomo BD9 touring chassis. This Arrowspace magnesium flex plate provides a controlled change in chassis stiffness so you can fine-tune handling and entry responsiveness.

Intended as a replacement or upgrade, the plate installs at the BD9's existing mounting points to keep original geometry intact. It adds an extra setup parameter for crews who use chassis flex to influence balance and corner entry on different surfaces.

Installation and care notes emphasise correct fitment: confirm the plate aligns with your chassis hardware, use suitable fasteners for magnesium, maintain clean contact areas, and check for signs of fatigue after heavy running.

AM-900005 gives BD9 owners a magnesium alternative for flex tuning, integrating with standard mounting and setup workflows for on-track adjustments.
