Technical note on the 2.5g dish for Mini 4WD

The M4WD-37/LB 2.5 gram dish weight from 3Racing is a precision-formed mass damper component intended for use as a replacement or tuning spare on Mini 4WD competition chassis. Its shallow dish geometry and light blue finish allow installation in constrained damper locations typical of MA, MS and AR series frames.

Classified as a passive mass element, the dish does not alter drivetrain or electronic systems. Its low profile minimises interference with adjacent components while providing a measured mass for balance adjustments and damping experiments during setup work. Builders should verify fastener type and hole spacing to ensure correct seating and repeatable installation.

Compatibility is determined by damper mounting arrangements; check mount diameter and clearance against the M4WD-37/LB dimensions before fitting. This technical overview addresses intended application and fitment considerations rather than claiming specific lap time improvements.

What mounting checks are recommended?

Measure the damper mount hole diameter and verify vertical clearance to adjacent components. Confirm whether your chassis uses screw-through or clamp-style retention to select the correct fastener length and type.

How does dish profile affect installation?

The shallow dish reduces protrusion above the mounting plane, allowing use in low-clearance positions and reducing the risk of contact with bodywork or bumpers during assembly and handling.

Recommended use cases for setup work?

Use the M4WD-37/LB as a trial mass when balancing front to rear or side to side, or when testing small damping changes. Keep spares on hand for quick swaps during trackside tuning sessions.

Any material handling notes?

Avoid overtightening fasteners which can deform the dish. If plating or coating specifications are critical for your workflow, consult the vendor for finish details before purchase.
