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

9g red cuboid ballast M4WD-39/RE

The M4WD-39/RE cuboid ballast is a compact 9g red weight designed to act as a simple mass element on Tamiya Mini 4WD cars. It is not a mechanical upgrade but a spare part for hobbyists focused on balance and mass distribution on standard 4WD Mini chassis.

Its cuboid form gives a clear, repeatable centre of mass and the 9g rating is suitable for incremental adjustments. The block fits locations that accept rectangular weights; no specialist mounting gear is assumed beyond common spare fittings.

The compatibility note limits usage to the item serving as a spare mass on Tamiya Mini 4WD platforms. Ensure you confirm fit and attachment method for your chassis and bodywork before final installation.
