This GPM set for Kyosho Mini-Z F1 provides front and rear foam tyre assemblies on Delrin hubs to support controlled setup trials. The configuration is aimed at making front/rear grip comparisons straightforward during tuning sessions.
Focus on fitment and alignment when installing rather than altering parts. Push each assembly onto the axle, check hub seating and wheel hex engagement, then spin to confirm free rotation. These are neutral tuning parts suited to hobbyist testing.
Use this Delrin-mounted foam tyre pair when you need consistent foam contact patches for comparative setup work on Mini-Z F1 cars, noting hub fit and rotation clearance each time.
