YZ-4S Graphite Center Mount Plate - S4-304CPA by Yokomo  [S4-304CPA]

Graphite center plate overview

This graphite center mount plate is made for the YZ-4S RC chassis. It acts as a direct replacement for the stock center mount, using graphite to modify center-section stiffness and adjust weight distribution on the model-scale chassis. The part is intended for RC-scale tuning and installs with the vehicle's existing mounting points.

Installation focuses on correct alignment and controlled torque rather than custom modifications. When fitting the plate, ensure the screw holes match the YZ-4S mounting pattern and tighten fasteners to the recommended thread engagement without over-tightening to prevent stressing the graphite. Check drivetrain clearance after fitting and verify chassis flatness on a bench to secure consistent handling.

Tuning role: switching to a graphite center plate typically raises central stiffness compared with softer plates, which can sharpen turn-in and reduce mid-corner body roll on track-oriented setups. Make incremental changes and use test runs to evaluate handling, pairing the plate with small suspension or damping adjustments to balance response.
