These alloy sinkage rims are an aftermarket wheel set for KYOSHO Mini-Z AWD models, identified by model MZA603F/R/+1.5. The rims feature a six-hole bolt pattern and are manufactured in aluminium to give secure tyre seating with common Mini-Z AWD wheel hubs.
Use case: these rims act as direct-fit hop-ups to change wheel offset and overall rim width on Mini-Z AWD cars. The specified 1.5mm offset shifts wheel placement laterally relative to stock, and the 8.5mm width supplies a clear bead area suitable for narrow or low-profile tyres aimed at circuit running.
Fitting advice: install with the existing wheel hex and retaining hardware from your Mini-Z AWD hub, confirm hex size compatibility prior to final torque, and tighten bolts progressively to protect the aluminium. Check tyre seating and balance after mounting, especially if you alter tyre type or add inserts.
Tuning guidance: adjusting offset and rim width will influence scrub radius and track width at model scale, which affects steering responsiveness and cornering balance. Make modest changes and evaluate the car on-track to refine handling.
