Kyosho Mini-Z AWD Rear knuckle arm holder (Toe Out -0.2mm) by GPM MZA031R/-0.2  [MZA031R/-0.2]

Rear knuckle arm holder for Mini-Z AWD

This alloy rear knuckle arm holder is an aftermarket replacement designed for Kyosho Mini-Z AWD micro touring platforms and MR-03 AWD variants, offered by GPM as model MZA031R/-0.2. It is produced as a single replacement piece and targets chassis tuning where precise toe settings at the rear axle affect turn-in balance and corner exit behaviour.

Functionally, the part provides a fixed toe-out offset of -0.2mm compared to standard geometry. That small toe change is used at the rear to influence transient handling; in practice it can alter rear-end bite and yaw response when adjusting a Mini-Z AWD setup for track conditions. The component is made from aluminium alloy to offer a stiffer mounting point than stock plastic parts, helping keep alignment consistent under load.

Installation notes: this item installs in place of the stock rear knuckle arm holder on compatible Mini-Z AWD MR-03 chassis; common workshop practice is to check bearing fitment and fastener torque after installation, and to verify wheel alignment on a setup board. No special tools beyond standard hex drivers are required, but inspect mating surfaces to avoid thread or bearing damage when swapping parts.
