This single-piece aluminium rear knuckle arm holder is a direct replacement for Kyosho Mini-Z AWD knuckle mounting and is supplied as one unit. The component uses a 0mm offset and a 1.0mm plate thickness as defined by the MZA031R/010G designation.
Engineered to provide a more rigid bearing surface than softer materials, the alloy plate reduces local flex at the knuckle interface and helps maintain consistent rear geometry under dynamic loads. This makes setup adjustments more predictable for club and track-oriented Mini-Z AWD tuning.
Installation follows the stock knuckle arm mounting pattern and installs using the vehicle's original fasteners, so no modification to the chassis layout is required. After fitting, inspect suspension travel and wheel alignment to verify correct clearance and camber behaviour.
