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

AM Medius front-drive conversion summary

This Arrowmax AM-920004 AM Medius FWD Conversion Kit adapts a Yokomo BD9 from its original drivetrain layout to a front-wheel-drive arrangement by using a 7075 aluminum chassis plate. The following notes cover platform compatibility, installation points to check, and how the kit affects handling and mass distribution for 1/10 on-road cars.

The core of the kit is the 7075 aluminum chassis plate referenced in the product title, which replaces or reinforces the BD9's chassis area that controls mounting geometry and structural stiffness. Typical installs shift front drivetrain mount locations and alter mass placement, so you should expect to rework suspension settings and overall weight balance after fitting.

Installation notes: this is a parts swap that requires precise alignment with existing Yokomo BD9 components. Confirm clearance and fit for your servo, motor and ESC positions, and body mounts before final assembly. After conversion, fine-tune ride height, toe, and anti-roll balance to regain predictable on-track behavior.
