Kyosho Mini-Z MR-03 AWD Rear Knuckle Arm Holder Precision Alloy Toe Out -0.4mm MZA031R-0410 by GPM  [MZA031R-0410]

Mini-Z AWD rear knuckle arm holder overview

This machined alloy rear knuckle arm holder is supplied for Kyosho Mini-Z AWD platforms as an aftermarket replacement or hop-up to adjust rear toe and refine steering feedback. The unit is specified at -0.4mm toe out and 1.0mm thickness, provided as 1 pcs suitable for single-side tuning changes.

Design and fit: CNC-style alloy construction increases rigidity compared with stock plastic parts and helps maintain alignment under load. It matches MR-03 AWD mounting points common to Mini-Z AWD chassis and installs in the OEM rear knuckle arm locations.

Tuning role: the -0.4mm setting moves rear tracking outward to influence rotation and mid-corner grip. Consider this part when seeking crisper turn-in or subtle adjustments to rear traction, and pair changes with roll centre and damper tweaks for balanced handling.

Installation notes: intended as an aftermarket component for Mini-Z AWD cars only. Verify fasteners and bearings during installation and re-torque mounting screws after a brief test run to confirm clearance and fit.
