KYOSHO Mini-Z AWD Track Sinkage Rims Front & Rear 6p 8.5mm Width MZA603F/R/+1.5 by GPM  [MZA603F/R/+1.5]

Sinkage rims for precision Mini-Z AWD setup

These aluminium sinkage rims are a replacement wheel set intended for KYOSHO Mini-Z AWD vehicles, designated model MZA603F/R/+1.5. The wheels utilise a six-hole mounting pattern and are made from aluminium to deliver a repeatable fit for typical Mini-Z AWD hubs.

Role: fitted as hop-up parts to change wheel offset and track behaviour on Mini-Z AWD models. The 1.5mm offset moves the wheel laterally versus factory items, while the 8.5mm rim width provides a distinct tyre bead area that aids when using narrow or low-profile tyres during track tuning.

Installation guidance: use the factory wheel hex and retaining hardware from your Mini-Z AWD hub, confirm hex compatibility before final tightening and torque gradually to avoid stressing the aluminium rim. Inspect tyre seating and balance after mounting or when you change tyre type or internal inserts.

Tuning impact: shifting offset and rim width will adjust the model-scale scrub radius and effective track width, which can alter steering weight and cornering behaviour. Implement small changes and test on the track to dial in handling.
