KYOSHO Mini-Z MR-015 Technical Body Holder KZ-14/3/BU by 3Racing  [KZ-14/3/BU]

Engineered MR-015 body holder

The KZ-14/3/BU is an engineered body retention component for KYOSHO Mini-Z MR-015 chassis and compatible Mini-Z shells, with validated fit for Ferrari 575 GTC style bodies. This technical summary focuses on fit tolerance, mounting behaviour and operational role within a Mini-Z platform.

Fit and role: the holder secures the painted shell to factory MR-015 body post positions, maintaining repeatable seating and preventing interference with chassis-mounted electronics and lighting. It is aimed at hobbyists and racers who require consistent shell positioning under repeated use.

Installation notes: install the holder using the MR-015s stock post locations without modifying the shell. Fine-tune holder placement to remove lateral play, check clearances for LEDs and antenna, and confirm uniform seating at every mount before final torque. No additional proprietary hardware is required; adhere to chassis service specifications for fastening torque values.

Tuning considerations: the holder affects body centring and can influence airflow and weight distribution in close racing. Incorporate the holder into setup cycles when changing shells or adjusting suspension geometry, and re-verify shell alignment after any suspension or mounting adjustments.
