This GPM set, produced for Kyosho Mini-Z F1, supplies front and rear foam-mounted tires seated on Delrin hubs intended for on-track model tuning. The parts are scale RC components designed to change front and rear grip balance, useful when testing traction settings or surface-specific setups.
Installation focuses on fit and alignment rather than modification. Confirm the hub seating and wheel hex engagement on your Mini-Z F1, slide the foam-mounted assembly onto the axle, and check for even seating and free rotation. These parts are neutral, service-oriented components for hobby-level tuning and test use.
Use this Delrin-mounted foam tire set when you need a predictable foam contact patch for comparative tuning on Mini-Z F1 setups, paying attention to hub fit and rotation clearance.
