This four-piece rim set is specified for Kyosho Mini-Z Monster models and carries the part reference MZM-001A/B. The dual-spoke geometry mirrors the Mini-Z Monster rim profile and is suitable for wheel swaps, visual setup, and tuning tasks that include tyre seating and minor mass distribution adjustments at the wheel level.
Declared fitment is Mini-Z Monster only. Installation follows the standard rim and tyre replacement routine for Mini-Z platforms: remove the tyre from the existing rim, refit to these rims, and reinstall the wheel assembly. No ESC, motor, or suspension modifications are required since these components function as wheel-level replacements.
Material and hardness are not listed in the source entry; verify with the vendor or the product label if a specific material property is necessary for your tuning goals. These rims are supplied as replacement/upgrade items for scale RC use and should be treated as cosmetic and setup components rather than drivetrain upgrades.
