Precision cuboid mass M4WD-39/LB for Mini 4WD

This 9g rectangular cuboid, finished in light blue, is supplied by 3Racing for use on Tamiya Mini 4WD cars. It is designed as a passive mass element to help hobbyists refine static weight distribution on compatible performance chassis. It does not perform active damping; rather it provides a compact, predictable ballast where space and mounting allow.

Fit and mounting are chassis dependent and influenced by any aftermarket parts fitted. Builders usually position a low-profile block where it can be fixed without interfering with rollers, drivetrain components, or body clearance. It is compatible with many Mini 4WD accessory holes and universal mass-damper brackets that accept small rectangular blocks.

The light blue finish is useful for visible mounting points and can complement aftermarket colour schemes. Always verify clearance and tighten fasteners before track sessions; consider this item a balance adjustment tool more than a performance upgrade in regulated competition.

Can I use this on high-downforce setups?

Yes, but the effect depends on placement relative to the centre of mass. Use small incremental changes and track testing to assess whether the additional mass helps or hinders high-downforce behaviour.

Is drilling required to fit the block?

Some installations use existing accessory holes or clamps and require no drilling. If you must drill, mark positions carefully and use appropriate drill bits for model chassis materials to avoid weakening the mount.

How durable is the finish?

The painted finish is fine for normal use and display, but repeated handling or abrasive contact around fasteners may cause wear. Consider protective measures if appearance is critical.

Will this affect lap times?

Extra mass can change acceleration and cornering. The net effect on lap times depends on the circuit and overall setup; test changes incrementally to find the optimum configuration.

Are replacement colours available?

Availability of other colours depends on the supplier. If a neutral or matching colour is important for your build, check stock or enquire about alternate finishes before ordering.
