Yokomo BD9 Conversion Kit 7075 Chassis for FWD - Arrowmax AM-920004  [AM-920004]

AM Medius FWD conversion brief

The Arrowmax AM-920004 AM Medius FWD Conversion Kit lets you change a Yokomo BD9 from its stock drivetrain to a front-wheel-drive layout using a 7075 aluminium chassis plate. The text below explains compatibility considerations, installation pointers, and the effects on handling and weight distribution for 1/10 on-road cars.

At the heart of the kit is the 7075 aluminium chassis plate called out in the product name, intended to replace or complement the BD9's chassis section that dictates mounting geometry and stiffness. Typical fitments alter front drivetrain mounts and component placement, so expect suspension and balance work after installation.

Fitment advice: this is a structural parts swap requiring accurate alignment with existing Yokomo BD9 hardware. Check servo and motor/ESC clearances and body mount positions prior to tightening fasteners. After fitting, adjust ride height, toe and roll distribution to recover a balanced handling feel.
