19g Brass Rear Mount for Yokomo B-MAX4 Arrowmax AM-MAX4-010  [AM-MAX4-010]

Rear Ballast Upgrade for Yokomo B-MAX4

Designed for the Yokomo B-MAX4 rear assembly, the Arrowmax AM-MAX4-010 is a 19g brass suspension mount that adds targeted mass to the back of the car. That added rear weight improves grip and steadies the chassis through fast changes of direction. The brass construction is both functional and resilient for regular track running.

How Brass Affects Vehicle Dynamics

Brass gives a compact way to alter weight distribution without changing suspension geometry. Installing this mount shifts the balance rearward on the Yokomo B-MAX4, which can tame snap oversteer and make the car more predictable on corner exits. It is a common tuning trick among racers looking for small but effective gains.

Practical Mounting Tips

Secure all mounting hardware when fitting the Arrowmax mount and confirm there is no interference with suspension travel. After a few runs, re-torque fasteners and verify alignment to keep handling consistent and components in good condition.
