This is a rear rim and tyre assembly optimised for Mini-Z AWD chassis, supplied as a single pair ready for installation. Wheel bodies are manufactured in Delrin with a wide ridge geometry for rear mounting, specified with a 5-hole pattern, 1.0mm offset and 11mm width, and the tyres are pre-mounted to the rims for immediate testing on compatible models.
Delrin provides stable dimensional tolerance and low surface friction ideal for repeatable wheel alignment at micro scale. The wider ridge alters rear track geometry compared to narrow original wheels, enabling targeted adjustments to rear traction and roll balance during setup and tuning sessions.
Install by replacing the factory rear wheels on compatible Mini-Z AWD hubs and reusing existing wheel fasteners and spacers. After fitting confirm clearance at body apertures and suspension details and verify tyre rotation is free from rubbing. Use this set to evaluate handling changes from modest offset and width adjustments.
