These 6p aluminium sinkage rims are supplied as a matched pair and carry the model designation MZA603F/R/+2.5. They are manufactured for Mini-Z AWD scale applications and fit many MR-03 AWD style chassis where hub spacing permits. Each rim is 8.5mm wide with a fixed 2.5mm offset, offering a stable, low-flex wheel profile compared with common plastic wheels.
As an aftermarket tuning component, these rims are intended to adjust stance and wheel location rather than promise specific dynamic gains. The 2.5mm offset shifts the wheel centre relative to the hub, which can alter track width and clearance; installers should confirm fit on their chassis before final assembly. The alloy construction provides improved rigidity for repeatable wheel geometry and simpler balancing.
Workshop guidance: fit the rims in place of the factory wheels and ensure a clean hub seat. Rotate each wheel to check for interference with suspension or the body shell, then secure with standard wheel retainers. Inspect for runout and perform a light balance where feasible to reduce vibration. Apply incremental changes when tuning and keep setup notes to maintain a known baseline.
