Yokomo BD9 FWD Chassis Carbon 2.25mm MM by Arrowmax AM-920021  [AM-920021]

AM Medius carbon chassis for BD9

This Arrowmax AM-920021 AM Medius chassis plate is an RC-scale replacement part built for tuning and setup work on Yokomo BD9 FWD touring car models. Made from 2.25mm carbon, the plate serves as a modular chassis option to alter stiffness and tune the car's handling characteristics on track or during practice sessions.

Performance role and installation notes: the component is intended as a direct RC hop-up for vehicles identified as Yokomo BD9, used to modify chassis rigidity and balance. Installers should verify mount alignment and hole locations against their existing BD9 chassis before fitting, and use original mounting hardware when possible. Changes to chassis stiffness affect suspension and steering feedback, so allow time for setup adjustments after installation.

For hobbyists and racers looking to adjust chassis stiffness on a Yokomo BD9, the AM-920021 provides a straightforward carbon option that integrates into setup workflows without introducing electronics or suspension parts.
