This 3Racing KZ-01B/WO graphite upper plate is an optional replacement part intended for Kyosho Mini-Z MR-015 scale models. It serves as a direct-style upper deck for the KZ-01/BU/WO chassis family, providing the same mounting footprint as the original upper plate while changing the stiffness and mass distribution where installed.
Installation is straightforward: the plate replaces the stock upper plate and uses the chassis' existing screw locations, so standard Mini-Z assembly steps apply. Verify screw lengths and clearances before final tightening to avoid contact with internal components such as the motor or electronics. No additional tools beyond typical Mini-Z maintenance tools are required.
As a tuning component, the graphite material increases torsional stiffness compared with thinner plastic decks, which helps concentrate setup adjustments on suspension and weight balance. Use it as part of a measured setup approach: swap the plate, test handling on a controlled surface, then adjust spring/damper or weight distribution incrementally to find the desired response.
