Mini-Z AWD MR-03 Rear Knuckle Arm Holder Alloy Toe In +0.1mm MZA031R/+0.1 by GPM  [MZA031R/+0.1]

Alloy rear knuckle arm holder for Mini-Z AWD

This aluminium alloy rear knuckle arm holder is an aftermarket replacement part made for Kyosho Mini-Z AWD setups, supplied as 1 pc. It delivers a +0.1mm toe in offset to alter the rear toe geometry without changing the upright or hub spacing.

In use the holder locates the rear knuckle arm to create the stated Toe In +0.1mm. On a Mini-Z AWD MR-03 chassis this is an incremental tuning change intended to sharpen turn-in and adjust in-corner balance on compact race layouts.

Fitting is straightforward for anyone familiar with Mini-Z maintenance: remove the original holder, install the alloy unit at the same mounting points, and secure with the existing fasteners. Use the correct hex driver, do not overtighten screws, and confirm alignment and clearance after fitting. Check adjacent bearings and parts when replacing plastic components.

A simple, lightweight upgrade for drivers seeking small but repeatable handling changes.
