Mini-Z MB-010 Optima Inner Foam Insert for Wheels - MBW004 by Kyosho  [KY-MBW004]

Replacement Kyosho MBW004 Inner Sponge (Optima) for Mini-Z MB-010 wheels

Compatibility notes

The MBW004 inner is intended for Optima-style tyre fitment on Mini-Z MB-010 chassis wheel assemblies. It is a component-level replacement that helps preserve internal support and the intended tyre profile used on these small-scale buggies.

Construction overview

Manufactured from a compliant foam, the insert is designed to sit between the tyre and wheel in Mini-Z MB-010 assemblies. Its dimensions and compressibility are chosen to align with the original geometry so tyre seating and shape stay consistent during running and storage.

Purpose and effect on handling

Functionally simple, the MBW004 supports the tyre carcass to maintain nominal shape under load and to prevent seating drift. In Mini-Z models, properly sized inners influence ride feel by keeping tyre shape stable during cornering and braking.

Intended user

This part suits hobbyists who restore or maintain Mini-Z MB-010 based machines and collectors seeking faithful replacement internals; it is intended to retain original specification rather than modify performance.

For accurate fitment on Mini-Z MB-010 wheels, the Kyosho MBW004 inner sponge provides consistent internal support and profile retention for those preserving original specs.
