This part is a performance-oriented body retention solution for the Kyosho Mini-Z MR-015, identified as model KZ-14/9/BU. It acts to reduce shell movement that can affect aerodynamic and weight distribution consistency during timed sessions.
Engineering and fit: the holder aligns to MR-015 chassis points and is intended to maintain repeatable shell placement, aiding in controlled testing and setup tuning without introducing extra variables.
Installation advice: verify accurate seating on the MR-015 mount points, use the recommended hardware or existing posts, and ensure the shell is centred before final torque. Small shell clearances may require trimming for an optimal fit.
Tuning impact: with stable shell anchoring you can more reliably evaluate shock rates, camber tweaks, and weight distribution changes, since body shift is effectively removed from the equation.
