Mini-Z MB-010 Inner Sponge Insert for Optima Tires - MBW004 by Kyosho  [KY-MBW004]

Kyosho MBW004 Inner Sponge (Optima): Fitment insert for Mini-Z MB-010 assemblies

Compatibility and platform

Designed for Optima-style tyres, the MBW004 inner fits the Mini-Z MB-010 chassis wheel assemblies. It is a component-level replacement intended to maintain the internal support and intended tyre profile on these models.

Build and materials

The insert uses a compliant foam selected to sit between tyre and wheel on Mini-Z MB-010 units. The geometry and compressibility are matched to the original design so tyre seating and contour remain consistent for running and storage.

Intended function

The primary role of the part is to support the tyre carcass, keeping the nominal profile under load and reducing the chance of seating shift. In scale buggies, inner inserts help keep tyre shape stable during cornering and acceleration.

Recommended audience

Owners restoring or preserving Mini-Z MB-010 models and collectors seeking correct-fit replacement internals will benefit from the MBW004; it is intended as a like-for-like replacement rather than a performance modification.

The Kyosho MBW004 is aimed at those who require accurate fitment and profile retention for Mini-Z MB-010 tyre assemblies, preserving original specification internals.
