MR-03 AWD Alloy Rear Knuckle Arm Holder +0.2mm Toe MZA031R/+0.2 by GPM  [MZA031R/+0.2]

Aluminium rear knuckle mount for MR-03 Mini-Z AWD

This replacement alloy rear knuckle arm holder for Kyosho Mini-Z platforms supplies a fixed +0.2mm rear toe-in correction to refine rear-end alignment. It is designed as an RC-scale hop-up for MR-03 AWD compatible Mini-Z layouts to help with subtle handling changes.

The component is tuning-focused: altering the knuckle mount geometry adjusts rear toe to influence turn-in and mid-corner balance without changing major suspension pieces. Expect a straightforward swap with compatible rear knuckle mounts, and verify fastener torque after a few runs.

As an aftermarket alloy mount, it gives a firmer attachment than standard plastic parts, cutting flex around the knuckle interface and keeping toe settings steadier under load during club runs or short-track practice. Treat this as a handling adjustment rather than a structural overhaul.
