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

Alloy rear knuckle arm holder for MR-03 Mini-Z AWD tuning

This alloy rear knuckle arm holder fits Kyosho Mini-Z AWD layouts and applies a fixed +0.2mm toe-in at the rear to help with handling adjustments. It is offered as an aftermarket tuning component for MR-03 AWD compatible chassis.

By shifting the knuckle mounting geometry the part changes rear toe characteristics to improve turn-in feel and mid-corner composure without needing to alter primary suspension items. Installation is typically a like-for-like swap; check alignment and fastener torque after a few runs.

As a metal upgrade over stock plastic mounts, it reduces flex at the knuckle connection and helps maintain toe settings under load in club and practice conditions. Use it as a fine-tuning adjustment for handling rather than a major chassis change.
