3Racing M4WD-39/BL cuboid weight for Mini 4WD layouts

This 3Racing M4WD-39/BL is a compact cuboid mass damper supplied in a black finish and specified at 9 grams. It is an aftermarket mass block intended for use with standard Mini 4WD bodies and frames where small, discrete weight additions are required. The component is simple by design: no integrated mounting hardware is included, and installation depends on the chassis layout and the builder's chosen attachment method.

Experienced hobbyists will use this part to fine tune static balance and local mass distribution rather than as a standalone performance upgrade. Because the item is an accessory mass damper, its effect depends on chassis geometry, roller placement, and overall setup. It is commonly applied to performance-oriented chassis where incremental weight changes are part of a broader tuning approach.

Compatibility considerations are practical: check clearance inside body shells, available mounting points, and whether added mass interferes with rollers or guide stay positions. The part is nominally described for Mini 4WD use; confirm fitment on the specific chassis before permanent attachment.
