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

Precision rear knuckle holder for Mini-Z AWD applications

This aluminium alloy rear knuckle arm holder is an aftermarket replacement crafted for Kyosho Mini-Z AWD platforms and is supplied as 1 pc. It introduces a controlled +0.1mm toe-in offset to adjust rear geometry without altering upright or hub spacing.

Designed to locate the rear knuckle arm accurately, the holder achieves the specified Toe In +0.1mm for incremental tuning on MR-03 chassis. The modest offset is useful for fine adjustments to turn-in and corner stability on short circuit formats.

Installation follows standard Mini-Z procedures: remove the original holder, locate the alloy unit in the same mounting points, and secure with the original fasteners. Use the correct hex driver, avoid excessive torque, and confirm alignment and clearance after assembly. Inspect adjacent bearings and linkages when replacing polymer components.

A practical, precisely made alloy upgrade for repeatable toe control in small-scale setups.
