Kyosho Mini-Z AWD Alloy Rear Knuckle Arm Holder (Toe Out -0.1mm) by GPM MZA031R/-0.1  [MZA031R/-0.1]

Rear Knuckle Arm Holder — Mini-Z AWD

This is an alloy rear knuckle arm holder designed for Kyosho Mini‑Z AWD platforms and intended for RC-scale tuning of the MR-03 AWD family. Supplied as 1 pcs, the part locates the rear knuckle and sets a -0.1mm toe out offset to alter rear-end behaviour without changing knuckle geometry.

Fitment focuses on MR-03 AWD style layouts; the component replaces the stock plastic holder with a machined aluminum piece to give a firmer mounting point for the knuckle arm. The part is an aftermarket replacement produced by GPM for Kyosho Mini‑Z AWD models and carries the GPM MZA031R/-0.1 identifier.

Installation notes: use the existing chassis mounting points and the stock fasteners unless a longer screw is required by your setup, check clearances with adjacent suspension links and ensure the toe offset is correct for your tuning goals. This holder is intended to be one element in suspension tuning, used to refine rear traction and transient response on small-track and carpet layouts.
