Mini-Z MR-03 AWD Rear Knuckle Mount Alloy Holder (Toe Out -0.3mm) MZA031R/-0.3 by GPM  [MZA031R/-0.3]

Overview of rear knuckle mount

This alloy rear knuckle arm holder is built for Kyosho Mini-Z AWD arrangements and suits MR-03 AWD style chassis. It fixes a rear toe-out of -0.3mm and is supplied as 1 pcs so you can replace one side or try asymmetric tuning experiments.

Its role is to secure the rear knuckle arm at the chosen toe setting. The alloy piece keeps the mounting position consistent while leaving other suspension elements unchanged, which is helpful when isolating toe effects during handling setup changes.

Fitment is intended as a direct swap for the OEM rear knuckle arm holder on compatible Mini-Z AWD cars; use the original mounting hardware and confirm clearance on MR-03 AWD variants before driving. Use this holder to make measured toe adjustments and judge their impact on corner entry and traction.
