The Yokomo Z4-118P graphite battery plate is an aftermarket replacement tailored to the YZ-4 family. It offers a slim, low-weight platform for battery installation and is intended as a direct swap where YZ-4 or B-YZ4 trays are used.
This plate is compatible only with the YZ-4 series supplied configurations: YZ-4 and B-YZ4 chassis variations. Constructed from graphite, it keeps mass low while maintaining adequate support for the pack during off-road use.
Fitting is simple for cars that already have removable battery plates: the Z4-118P mounts to the existing battery-mount points and uses the original fasteners. Confirm screw lengths and check for any potential interference with nearby components when fitting.
On the setup side, a graphite plate influences the vehicle's centre of mass and flex characteristics. Treat the plate as a tuning item to adjust front/rear bias and to evaluate changes in roll and traction independently of other hardware changes.
