These are scale alloy front and rear sinkage rims produced for Kyosho Mini-Z AWD platforms, supplied as one pair and identified as GPM MZA503F/R/+2.5. The item carries the original dimensional notes in the product name: 5p, 2.5mm offset, and 8.5mm width. The construction is aluminium alloy, intended as an RC-scale wheel upgrade rather than a factory replacement part.
The rims are intended to give a precise mounting surface for Mini-Z tyres and to allow small changes in track width and tyre placement via the 2.5mm offset. On MR-03 AWD style layouts this type of rim helps with tyre seating and matching low-profile bodies where wheel tuck and clearance are sensitive to rim width and offset.
Installation is typical for Mini-Z wheel swaps: remove the existing wheel from the hex hub, fit the alloy rim and ensure the wheel hex and any spacers align correctly. Use standard Mini-Z wheel hexes and follow model-specific torque and clearance checks. This product is for RC model tuning and tyre-fitment work only.
