Yokomo B-MAX4 III Carbon Chassis Plate for Low-Bite Setup - Arrowmax AM-MAX4-011  [AM-MAX4-011]

Lightweight Carbon Base for Yokomo B-MAX4

The Arrowmax AM-MAX4-011 is a direct-replacement carbon fibre chassis plate made for the Yokomo B-MAX4 III platform, supplied to adjust chassis flex and heat behaviour for race-specific setups. Constructed from Arrowmax Q-Grade multi-directional carbon, the plate targets improved transverse stiffness compared with many single-direction plates while keeping mass down for nimble handling.

Measured differences versus the stock chassis include a notable drop in mass from roughly 127g to approximately 66g, plus a shift in flex that emphasises mid-to-low bite compliance for certain surface conditions. A honeycomb-pattern recess under the motor pocket is integrated to promote airflow beneath the motor and aid temperature management during longer runs.

Fitment is direct-replace, maintaining the factory mounting points and fastener locations used by the B-MAX4 III layout. During installation, verify screw torque and clearances around the motor pocket and nearby electronics to preserve intended airflow through the honeycomb openings. The plate changes tuning by combining reduced weight with tuned transverse stiffness, making it suitable for lower-grip circuits or setups needing extra controlled flex.

For builders chasing a lighter, differently tuned carbon base for the B-MAX4 III, the AM-MAX4-011 offers focused transverse stiffness from multi-directional carbon and a motor-area honeycomb to assist cooling, all in a direct-replace fit that keeps original mounting geometry.
