YZ-4S Rear Chassis Stiffener Plate, Graphite - S4-003RC by Yokomo  [S4-003RC]

Graphite stiffener for the YZ-4S rear section

Designed as an RC-scale add-on, this graphite rear chassis brace mounts onto the resin rear chassis support of the YZ-4S. The graphite element spans the resin brace to reduce flex and strengthen the rear chassis area.

Mounting is done with the resin brace's existing screw locations: set the plate in place over the support and use the original fasteners to attach it. No cutting or permanent changes to the primary chassis are required for installation.

When used in setup work, the graphite plate increases rear stiffness and alters the car's handling balance. Expect a firmer rear that affects traction and yaw characteristics, making it a useful tool for dialling in stability without touching suspension arms or drivetrain parts. Intended for model-scale RC use only.
