Yokomo B-MAX4 III Performance Carbon Plate Upgrade - Arrowmax AM-MAX4-011  [AM-MAX4-011]

Performance Carbon Plate for B-MAX4 III

The Arrowmax AM-MAX4-011 is a drop-in carbon fibre chassis plate tailored for the Yokomo B-MAX4 III chassis to modify flex behaviour and thermal characteristics for particular track demands. Manufactured from Arrowmax Q-Grade multi-directional carbon, the plate aims to deliver increased transverse stiffness while keeping mass low for sharper response.

Compared to the original plate, measurable changes include a decrease in mass from roughly 127g to around 66g and an altered flex profile that supports more mid-to-low bite compliance. A honeycomb-patterned recess under the motor pocket is incorporated to channel airflow across the motor and assist cooling during sustained running.

Installation follows a direct-replace approach, retaining factory screw locations and mounting points for the B-MAX4 III layout. When fitting, confirm fastener torque and check clearances near the motor pocket and electronics to maintain the designed airflow through the honeycomb apertures. The plate adjusts chassis tuning by combining reduced weight with tuned transverse stiffness, which is useful for lower-grip circuits or setups that want more predictable flex.

For drivers focused on lower-grip tracks or those wanting a lighter, specially tuned carbon plate for the B-MAX4 III, the AM-MAX4-011 pairs multi-directional transverse stiffness with a motor-area honeycomb for better airflow, while keeping standard mounting geometry unchanged.
