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

Graphite rear chassis brace for YZ-4S

This graphite rear chassis brace is an RC-scale accessory designed to mount onto the resin rear chassis support of the YZ-4S platform. Its purpose is to increase rear chassis stiffness by adding a rigid graphite element across the resin brace, reducing local flex at the rear section of the chassis.

Installation is straightforward when paired with the original resin brace: the plate is positioned over the support and fastened using the existing mount points on the chassis support. No additional modifications to the primary chassis are required beyond using the matching screw locations on the resin brace.

In tuning terms, adding this graphite brace shifts the rear stiffness profile. Expect a firmer rear end that can change traction and yaw response; drivers use it as a modular way to fine‑tune balance between chassis compliance and stability without altering suspension or drivetrain components. This part is explicitly an RC component and intended only for model-scale setups.
