This is an alloy rear knuckle arm holder for Kyosho Mini-Z AWD models, supplied as part MZA031R+0210. The 1.0mm alloy construction reduces flex compared with factory plastic parts and provides a fixed 0.2mm toe-in reference for micro touring tuning.
Role in setup: intended for racers and tuners who need reproducible rear toe geometry. By locking in a small toe-in, the bracket helps control rear tracking and corner entry balance on tight, scaled circuits.
Installation advice: fits into the stock Mini-Z AWD rear knuckle area and uses the car's existing mounting points and screws. Double-check screw lengths and torque values when assembling alloy to plastic components to prevent thread damage.
Sold as a single piece, designation MZA031R+0210, useful for hobbyists performing model-level repairs and alignment upgrades on Kyosho Mini-Z AWD cars.
