This graphite center mount plate is produced for the YZ-4S RC chassis and suits the B-YZ4SF layout. The component uses graphite to alter center stiffness and weight balance for tuning purposes. Fitment is intended on the chassis' standard mounting points.
During installation concentrate on alignment and correct torque values rather than fabricating new mounts. Verify that screw holes align with the YZ-4S pattern and tighten fasteners to recommended engagement without over-stressing the graphite. After installation confirm drivetrain clearances and check the chassis is flat on a bench to ensure predictable handling.
On handling: installing a graphite center plate typically stiffens the center relative to softer plates, which can improve turn-in responsiveness and lower mid-corner body roll on race setups. Introduce adjustments gradually and run test laps to gauge changes, combining the plate with minor suspension or damping tweaks to find the best balance.
