Kyosho Mini-Z MR-03 AWD Rear Knuckle Arm Holder Alloy -0.4mm Toe 1.0mm MZA031R-0410 by GPM  [MZA031R-0410]

Mini-Z AWD rear knuckle arm replacement

This alloy rear knuckle arm holder is intended for Kyosho Mini-Z AWD cars as an aftermarket replacement or tuning option to alter rear toe and enhance steering feel. The specification lists -0.4mm toe out and a 1.0mm thickness, with the part supplied as 1 pcs for one-side replacement or targeted setups.

Design and fit: the machined aluminium body provides greater stiffness than stock plastic, helping to hold wheel alignment under load. It is made to suit MR-03 AWD configurations used across the Mini-Z AWD family and installs into the standard rear knuckle arm positions.

Tuning role: setting rear toe to -0.4mm shifts tracking slightly outward to affect rotation and mid-corner grip. Fit this part when you want a sharper turn-in or to tweak rear traction, and always combine geometry changes with suspension tuning rather than relying on a single modification.

Installation notes: this is an aftermarket alloy component for RC Mini-Z AWD use. Check fasteners and bearings during fitting, and re-check torque after a short run to ensure correct fit and clearance.
