Mini-Z MR-03 AWD Rear Knuckle Arm Holder (Toe -0.2mm, 1.0mm) MZA031R-0210 by GPM  [MZA031R-0210]

Mini-Z MR-03 alloy rear knuckle holder

This alloy rear knuckle arm holder is an aftermarket replacement part for Kyosho Mini-Z AWD vehicles, supplied as 1 pcs. The specified geometry provides a -0.2mm toe out and a 1.0mm thickness, intended to replace the stock rear knuckle mounting on MR-03 AWD chassis.

Fit and installation notes: built for Kyosho Mini-Z AWD MR-03 AWD applications, confirm your chassis variant before fitting. Most installs reuse the original retaining screws and standard Mini-Z wheel hub hardware; mount on a clean surface and use the same fastener torque as the stock holder to maintain alignment.

Tuning role: the holder alters rear toe geometry and is useful during setup changes aimed at rear steering response or balance. Because it is alloy, expect a firmer mounting than factory plastic parts which can alter handling feedback; make incremental toe adjustments and retest on a safe surface.

Material and care: made from alloy; remove dirt after sessions and inspect screw interfaces regularly. Replace the holder if threads or bearing seats show significant wear.
