Kyosho Mini-Z AWD Rear Knuckle Arm Holder 0.6mm Toe Out -0.4mm MZA031R-0406 by GPM  [MZA031R-0406]

Alloy rear knuckle mount for Mini-Z AWD tuning

This GPM aftermarket single-piece alloy rear knuckle arm holder is designed for Kyosho Mini-Z AWD platforms, manufactured to a consistent 0.6mm thickness and built to provide -0.4mm rear toe out. Supplied as 1 pcs, it replaces the stock plastic mount when a stiffer alloy option is wanted for sharper cornering control and steadier toe geometry under load.

The part is tuning-focused rather than decorative: alloy construction reduces flex at the knuckle pivot so the rear suspension holds toe settings more consistently through repeated laps. It fits Mini-Z AWD setups that use the MR-03 AWD style knuckle pattern; confirm chassis compatibility before fitting.

Installation tips: fit with the factory fasteners, verify thread engagement and alignment, re-check toe after installation, and avoid over-torque to protect bearings and shafts. Supply count: 1 pcs.
