The M4WD-05/PK is a single-piece 9.4 gram reference mass intended for technical evaluation of inertia placement on Mini 4WD platforms. Its compact form factor allows precise comparative testing of damper locations without introducing additional assembly variables.
Use case: install the weight at designated damper attachment points to record handling differences and balance shifts during setup runs. The coloured finish aids visual consistency across multiple test rigs and matched builds. The component is supplied as the mass only and does not include mechanical damper internals or drivetrain parts.
Installation considerations: verify mounting hole centres, plate thickness and adjacent clearance before permanent fixing. For repeated testing use non-permanent fixings or dedicated test brackets to preserve component and chassis condition.
Material and specification note: nominal 9.4 gram single coloured mass aimed at hobbyists and competitive tuners evaluating component interchangeability and mass distribution effects.
