Kyosho Mini-Z AWD Rear knuckle arm holder - Aluminium (Toe Out -0.2mm) - MZA031R/-0.2 by GPM  [MZA031R/-0.2]

Rear knuckle arm holder for Mini-Z AWD tuning work

This aluminium rear knuckle arm holder is an aftermarket replacement compatible with Kyosho Mini-Z AWD micro touring cars and MR-03 AWD chassis, identified as model MZA031R/-0.2. It is supplied as a single replacement piece for builders who tune rear toe to refine handling balance.

The holder delivers a fixed -0.2mm toe-out compared to standard geometry. That subtle rear toe change can alter transient behaviour, shifting rear bite and yaw characteristics to suit different indoor or outdoor micro racing surfaces. The aluminium alloy construction offers a firmer mounting point than stock plastic, helping alignment remain consistent during spirited running.

Fitment notes: installs in place of the original rear knuckle arm holder on compatible MR-03 AWD layouts. After installation check bearing fit and torque settings, then re-check wheel alignment on a setup board. Typical shop tools are sufficient for the swap.
