This Yokomo Z4-118P graphite battery plate is an RC-scale replacement part designed for the YZ-4 family. It provides a low-mass mounting surface for your battery and is intended as a direct-fit upgrade where YZ-4 or B-YZ4 battery trays are specified.
Compatibility is limited to the YZ-4 series as supplied: YZ-4 and B-YZ4 chassis platforms. The plate is fabricated from graphite to keep weight low while maintaining structural support for the battery pack during off-road runs.
Installation is straightforward on machines already configured for a removable battery plate: the Z4-118P installs using the existing battery-mounting points and fasteners on the YZ-4 tray. Check screw lengths and thread engagement when swapping parts to avoid interference with nearby components.
From a setup perspective, a graphite plate affects the car's centre of mass and flex characteristics. Use the plate as a tuning tool to fine-tune front/rear balance and to test changes in roll and traction without introducing other hardware variables.
