This pair of Delrin wheels with tyres is intended for Mini-Z AWD chassis and is listed as model DMZA601RW888. The rims are injection molded Delrin, specified as 6p with 0mm offset and an 8.3mm width, supplied pre-mounted to simplify setup for indoor running.
Fitment notes: confirm rear hex and hub type on the target Mini-Z AWD vehicle before fitting. Replace the factory rear wheels with this set using the existing wheel retaining hardware and verify concentricity and runout after installation. The 0mm offset and 8.3mm flange width should be checked against bodyshell clearance and suspension link geometry on MR-03 AWD style cars.
Performance and tuning: these wider rear rims modify tyre profile and contact patch to alter rear traction characteristics for carpet or indoor tracks. The Delrin material provides dimensional stability for repeatable tyre fitment and balancing; adjust tyre compound and inner support to achieve the desired rear grip and handling balance.
