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

Graphite rear brace for YZ-4S chassis

This graphite rear chassis brace is an RC accessory made to fasten onto the resin rear chassis support of the YZ-4S. It increases rear chassis stiffness by adding a rigid graphite element over the resin support, reducing local flex at the rear section.

Fitting is simple when used with the original resin brace: position the plate over the support and secure it with the existing mount points. No alterations to the main chassis are required beyond using the matching screw holes on the resin support.

From a tuning perspective, installing this graphite plate moves the rear stiffness curve toward a firmer feel. Expect changes to traction and yaw response as the rear becomes less compliant; racers and hobbyists use it as a modular way to adjust balance without altering suspension or drivetrain parts. This item is intended solely for model-scale RC use.
