Kyosho Mini-Z AWD Alloy Rear Knuckle Arm Holder (Toe In +0.2mm) by GPM MZA031R/+0.2  [MZA031R/+0.2]

Alloy rear knuckle arm holder for Mini-Z AWD

This GPM replacement part, produced for Kyosho Mini-Z platforms, is an alloy rear knuckle arm holder that provides a fixed +0.2mm toe-in correction for the rear end. It is intended as an RC-scale hop-up to fine-tune rear alignment on Mini-Z AWD cars using MR-03 AWD-compatible layouts.

The part's role is tuning-focused: by changing the rear knuckle mounting geometry, it alters rear toe characteristics to help balance turn-in and mid-corner stability without modifying bulk suspension components. Installers should expect a direct swap with existing rear knuckle mounts on compatible Mini-Z AWD setups and check fastener torque after a few runs.

As an aftermarket alloy component, it offers a stiffer mounting point compared with stock plastic parts, which can reduce flex at the knuckle interface and keep toe settings more consistent under load during club runs or short-track practice sessions. Treat this as an RC-scale adjustment item for handling tuning only.
