This wheel set is a Delrin front and rear ridge rim assembly supplied with tyres fitted to the rims, sold as a 1pr set and noted on the pack as 5p, 1.5mm offset and 8.3mm width. It is made for the Kyosho Mini-Z AWD platform and intended as an aftermarket upgrade or replacement for Mini-Z AWD cars.
Delrin rims give a low-friction, lightweight option for small-scale wheels. The ridge profile helps keep mounted tyres from slipping on narrow rims commonly used on Mini-Z AWD chassis. Fitted tyres arrive mounted to simplify setup so you can check fit and handling straight away after mounting.
Fitting on Mini-Z AWD hubs is straightforward: remove the original wheel, confirm hex fit and orientation, then fit the rim and secure with the stock wheel nut or hex screw. With a 1.5mm offset and 8.3mm width, verify clearance around body posts and suspension travel before final tightening to prevent rubbing.
Handling notes: switching to these Delrin ridge rims changes the contact patch behaviour compared with foam or soft rubber race wheels, often giving sharper turn-in on tight indoor layouts. Use them when you want predictable grip and minimal tyre squirm for precise steering, and match tyre compound to the surface for best results.
