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

Precision alloy rear knuckle arm holder for Mini-Z AWD

This alloy rear knuckle arm holder is an aftermarket upgrade for Kyosho Mini-Z AWD cars, supplying a fixed +0.2mm toe-in at the rear to refine handling characteristics. It suits MR-03 AWD compatible chassis arrangements as a tuning item.

Functionally it adjusts the rear knuckle mounting geometry to alter toe behaviour, helping to tune turn-in and mid-corner balance without changing bulk suspension parts. Fitment is generally a direct swap on compatible Mini-Z AWD mounts; recheck torque after initial runs.

As a metal replacement for plastic mounts, it reduces movement at the knuckle interface and keeps toe settings more consistent under load during practice or club meetings. Use it as a handling tuning tool rather than a structural upgrade.
