Kyosho Mini-Z AWD rear knuckle arm holder (Toe Out -0.2mm, Thick 1.0mm) by GPM MZA031R-0210  [MZA031R-0210]

Mini-Z AWD rear knuckle arm holder

This alloy rear knuckle arm holder is an aftermarket replacement part designed for Kyosho Mini-Z AWD platforms, supplied as 1 pcs. Its listed geometry provides a toe out of -0.2mm with a thickness of 1.0mm, and it is intended for use on MR-03 AWD chassis where owners want a direct swap for the stock rear knuckle mounting point.

Fit and installation notes: the part is produced for Kyosho Mini-Z AWD MR-03 AWD applications, so verify chassis variant before installation. Standard Mini-Z wheel hub hardware and the original retaining screws are typically reused; install on a clean mounting surface and torque fasteners to the same values used on the stock alloy or plastic holder to preserve alignment.

Tuning role: this knuckle arm holder affects rear toe geometry and can be used as part of a setup change when adjusting rear steering sensitivity or balance. Because the item is alloy, expect firmer mounting compared with plastic stock pieces, which can alter feedback and consistency during repeated runs. Use small incremental adjustments when changing toe and confirm handling on a controlled test surface.

Material and care: made from alloy, clean debris after sessions and inspect screw points for looseness. Replace if threads or bearing seats show excessive wear.
