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

Rear knuckle arm holder briefing

This alloy rear knuckle arm holder is intended for Kyosho Mini-Z AWD applications and aligns with MR-03 AWD mounting patterns. The component sets the rear toe-out at -0.3mm and is supplied as 1 pcs to support single-side swaps or tuning trials.

The holder locks the rear knuckle arm into the selected toe geometry. Alloy construction minimises flex at the mount so toe adjustments remain consistent while other suspension components are left unchanged, ideal for controlled testing of alignment effects.

Install as a direct replacement for the standard rear knuckle arm holder on compatible Mini-Z AWD cars; reuse the original hardware and confirm clearance on MR-03 AWD variants prior to running. Employ this part to perform measured toe tweaks and observe their influence on corner entry and mid-corner traction.
