Arrowmax AM-910004 mid-motor conversion for Yokomo BD9

The Arrowmax AM-910004 AM Medius Yokomo BD9 MID Conversion Kit is a robust upgrade aimed at drivers who want to refine the handling of their Yokomo BD9. Machined from durable 7075 aluminum, the chassis conversion helps create a more consistent platform for tuning and race setups.

Benefits of the Arrowmax AM Medius MID conversion

This kit is built to integrate cleanly with the Yokomo BD9 layout, delivering precise fitment and reliable assembly. The 7075 aluminum construction increases rigidity and shifts mass toward the centre, which helps balance traction and steering feel.

On-track advantages

Switching to the mid-motor layout reduces pronounced weight transfer during acceleration and braking, improving corner entry and exit. Drivers will notice crisper response and steadier mid-corner behaviour, useful for tight club and regional racing.
