This alloy rear knuckle arm holder is produced as part MZA031R+0210 for Kyosho Mini-Z AWD cars. The 1.0mm alloy plate is engineered to reduce flex at the rear knuckle mounting area and to hold a repeatable 0.2mm toe-in reference for tuning and setup work.
Engineering summary: the component establishes a firm hardpoint for rear knuckle geometry, making toe settings repeatable across runs and reducing variation caused by softer plastic mounts. It is intended for model-level suspension tuning on micro touring and Mini-Z AWD race configurations.
Installation notes: fits into the stock Mini-Z AWD rear knuckle location and uses existing mounting hardware. Verify screw engagement and apply conservative torque values when fastening alloy to plastic to maintain long-term fitment.
Package: single unit, GPM designation MZA031R+0210, supplied for maintenance, alignment control, and precise setup adjustments on Kyosho Mini-Z AWD vehicles.
