This pair of Delrin front and rear ridge rims is made for Mini-Z AWD platforms and is presented as a direct aftermarket wheel option by GPM DMZA601F/R/0. The rims are molded in Delrin to provide a low‑mass wheel seat that keeps rotational inertia down while maintaining dimensional stability for small‑scale setups.
Use these rims where narrow 8.5mm wheel widths and 0mm offset are required — common in scaled indoor sprint and short‑track layouts. The ridge profile is intended to help tyre seating and alignment on small‑diameter tyres, giving consistent contact patch placement and easier tyre change handling.
Installation notes: these wheels work with Mini-Z AWD hubs that accept the same wheel hex and bore dimensions, and they are typically pressed or secured with the stock hex screw and wheel nut arrangement used on Mini‑Z AWD conversions. Check hub clearance around the suspension and steering links before final fitting to avoid interference.
Setup and tuning role: swapping to Delrin rims of this width and offset alters effective tyre track and rotating mass, which can influence turn‑in and mid‑corner balance. Use them when you want a stable tyre seat and small reductions in rotational inertia for quicker transient response on tight circuits.
