Yokomo BD9 Aftermarket FWD Chassis Plate 7075 - Arrowmax AM-920004  [AM-920004]

AM Medius FWD conversion notes

The Arrowmax AM-920004 AM Medius FWD Conversion Kit converts a Yokomo BD9 from its standard drivetrain into a front-wheel-drive arrangement by installing a 7075 aluminium chassis plate. The passage below outlines compatibility, what to verify during installation, and how the kit affects handling and mass distribution for 1/10 on-road vehicles.

The primary component is the 7075 aluminium chassis plate referenced in the title, intended to replace or reinforce the BD9 chassis section that controls mounting geometry and torsional characteristics. In common installations the kit modifies front drivetrain mounting points and relocates mass, so be prepared to revise suspension setup and balance following installation.

Fitting advice: this conversion is a parts swap that requires accurate alignment with existing Yokomo BD9 components. Confirm servo, motor and ESC clearances along with body mount positions before final assembly. Expect to fine-tune ride height, toe and roll stiffness to recover consistent handling after the change.
