Kyosho Mini-Z AWD Rear Knuckle Arm Holder (Alloy, Toe Out -0.4mm, Thick 1.0mm) by GPM MZA031R-0410  [MZA031R-0410]

Mini-Z AWD rear knuckle holder

This GPM alloy rear knuckle arm holder is made for Kyosho Mini-Z AWD platforms and is intended as a direct replacement or hop-up part to adjust rear toe and improve steering feedback. The part specifies a toe out of -0.4mm and a thickness of 1.0mm, supplied as 1 pcs for single-side replacement or specific tuning swaps.

Design and fit: the machined alloy construction offers a firmer mounting point compared with stock plastic pieces, helping to keep wheel alignment consistent under load. It is compatible with MR-03 AWD configurations noted for Mini-Z AWD series, and installs in the same mounting positions as the original rear knuckle arm holder.

Tuning role: the -0.4mm toe out setting shifts rear tracking slightly outward to influence rotation and mid-corner grip. Use this part when tuning for quicker turn-in or to alter rear traction characteristics; pair adjustments with roll center and shock settings rather than changing multiple geometry items at once.

Installation notes: this is an aftermarket alloy component intended for RC-scale Mini-Z AWD use only. Check existing fasteners and bearings during swap, and re-torque mounting hardware after a short test run to confirm fit and clearances.
