GPM MR-03 Kyosho Mini-Z AWD Rear Knuckle Arm Holder MZA031R-0210  [MZA031R-0210]

Rear knuckle arm holder for Mini-Z AWD

This alloy rear knuckle arm holder is an aftermarket replacement made for Kyosho Mini-Z AWD platforms and is supplied as 1 pcs. The part keeps the specified geometry with a -0.2mm toe out and a 1.0mm thickness, intended as a direct-fit option for the MR-03 AWD rear knuckle mounting point.

Fit and installation notes: produced for Kyosho Mini-Z AWD MR-03 AWD applications, confirm your chassis code before fitting. Standard Mini-Z wheel hub hardware and the original retaining screws are normally reused; fit the holder onto a clean mounting surface and torque fasteners to the same values used on stock alloy or plastic holders to keep alignment intact.

Tuning role: this knuckle arm holder directly influences rear toe geometry and can be used when refining rear steering sensitivity or balance. The alloy construction gives a firmer mounting compared with plastic stock parts, which may change feedback and repeatability during multiple runs. Make small incremental changes when altering toe and validate handling on a controlled surface.

Material and care: manufactured from alloy, clear away grit after sessions and check screw holes for looseness. Replace the part if threads or bearing seats show excessive wear.
