Engineered by GPM for Kyosho Mini-Z F1 applications, this set provides front and rear foam-mounted tyres on CNC-quality Delrin hubs to aid controlled tuning. The assemblies are intended for repeatable comparative testing of traction and balance across different track conditions.
Installation requires correct seating of the Delrin hub and proper wheel hex engagement on the Mini-Z F1 axle. Fit each assembly, verify axial clearance and free rotation, and confirm there is no interference with suspension or bodywork. These upgrade components are aimed at hobbyists seeking predictable foam contact patches for setup work.
Use these Delrin-mounted foam tyres for methodical grip comparisons and tune validation on Mini-Z F1 models, paying attention to hub seating and rotation clearance during installation.
