Kyosho MBW005 LAZER Inner Sponge for Mini-Z MB-010 - Purpose and Fitment

Role on the Mini-Z MB-010 chassis

The MBW005 inner sponge installs inside LAZER-marked Mini-Z tires used on the MB-010 platform to help the tyre keep a predictable cross-section under load. It is a focused service part that supports consistent handling rather than altering chassis geometry.

Design and material characteristics

Made from closed-cell foam, the insert is cut to match common Mini-Z tyre interiors for the MB-010. The material balances shape retention with moderate rebound so the tyre maintains section and returns reliably between runs.

How this part affects tire behavior in practical terms

Stabilising the tyre profile reduces unwanted deformation and helps create a repeatable contact patch. That repeatability makes steering and throttle inputs feel more consistent across sets of tyres and between sessions.

Who this part is aimed at

Builders and collectors running LAZER Mini-Z tyres on MB-010 chassis who want a simple replacement or spare insert will find the MBW005 useful for maintaining predictable tyre performance.

As a straightforward replacement component, the Kyosho MBW005 inner sponge helps preserve tyre profile and delivers steadier behaviour for LAZER Mini-Z tyres on the MB-010 chassis.
