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

Rear tuning mount for B-MAX4

This compact upgrade for the Yokomo B-MAX4 chassis is supplied by Arrowmax as model AM-MAX4-010 and is machined from brass with a nominal mass of 19g. It is intended to shift rear-end weight and adjust suspension response for more consistent on-track handling.

Fit this mount when you want a repeatable method to add mass at the rear suspension area during setup work. The added weight changes rotational inertia and short-term rear response, which can help when balancing handling on carpet or asphalt club circuits. The part is sized specifically for model car use.

Installation tips: secure the mount to the rear suspension mounting points on a Yokomo B-MAX4 chassis, confirm thread type and screw length before final tightening, and recheck suspension travel after fitting. Make setup changes one at a time and record ride-height and body-roll to isolate the mount's influence.

For focused setup sessions, this brass rear mount provides a straightforward, removable way to experiment with rear mass and handling on a Yokomo B-MAX4; measure changes to judge effectiveness.
