Tamiya Mini 4WD Red Cuboid 9g Mass Block M4WD-39/RE by 3Racing  [M4WD-39/RE]

Red cuboid 9g mass block M4WD-39/RE

The M4WD-39/RE cuboid mass block is a compact red 9g weight intended as a simple ballast for Tamiya Mini 4WD models. It is described purely as a mass element, aimed at hobbyists adjusting balance and weight distribution on standard 4WD Mini chassis without altering mechanical systems.

The cuboid profile yields a reliable centre of mass, and the 9g nominal weight is suited to modest, repeatable adjustments. The shape is intended for spots where rectangular blocks are accommodated; the description does not assume specific materials or bespoke mounting hardware.

Compatibility notes restrict the part to use as a spare mass item for Tamiya Mini 4WD platforms. Prior to installation, builders should confirm fitment and attachment methods for their selected chassis, and collectors can use the red colour as a visual spare identifier.
