The Kyosho MZW415B Aluminium Upper Arm Set boosts the responsiveness of the Mini-Z MR-03 by replacing flexible plastic arms with aluminium parts. The change delivers a more direct spring effect that aids stability through turns.
These aluminium upper arms offer greater stiffness than the original plastic pieces, resulting in steadier suspension action and more accurate steering inputs. That makes them a practical choice for racers and enthusiasts alike.
Installing the Kyosho MZW415B is approachable for hobbyists and requires only common RC tools. After fitting you should notice improved cornering control and more predictable traction on different surfaces.
