Mini 4WD Low-Profile Bowl Weight 3.5g M4WD-07/GO replacement part by 3Racing  [M4WD-07/GO]

The 3Racing M4WD-07/GO is a small bowl-shaped mass damper with a nominal mass of 3.5 grams, intended for use on Mini 4WD cars. It is supplied as a replacement or spare for those maintaining Tamiya Mini 4WD chassis, offering a compact form suited to shallow mounting points.

Think of this piece as a service component rather than a tuning kit; the emphasis is on compatibility and straightforward swapping. Builders should inspect their damper cup and fasteners to ensure the M4WD-07/GO will seat correctly without requiring bodywork or forced modification.

For collectors it helps keep models period-correct, and for regular racers or hobbyists it functions as an unobtrusive mass option for balance testing or preserving original equipment fitment.
