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

Rear mass mount suited to B-MAX4

This small-scale upgrade for the Yokomo B-MAX4 is supplied by Arrowmax as model AM-MAX4-010 and manufactured from brass with a listed weight of 19g. It is used to alter rear mass distribution and influence how the rear suspension responds during dynamic manoeuvres.

Use the mount when you need a controlled way to add weight to the rear suspension area while working through setup options. The additional mass affects rotational inertia and transient rear behaviour, which can be helpful when refining balance on carpet or sealed surfaces. The component is intended for model car tuning only.

Fitment notes: attach to the rear suspension mounting points on a Yokomo B-MAX4 chassis, confirm screw thread and length prior to final assembly, and re-evaluate suspension travel and droop after fitting. Make incremental changes and log results to isolate the mount's effect.

As a simple tuning accessory, this brass rear mount lets you experiment with rear weight and handling on a Yokomo B-MAX4 in a reversible way; use measured laps to confirm changes.
