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

Reinforcing graphite plate for YZ-4S rear

This graphite rear brace is an accessory intended to mount over the resin rear chassis support on the YZ-4S platform. Its role is to provide a stiff graphite span across the resin brace to limit local flex at the chassis rear.

Installation is straightforward with the OEM resin support: lay the plate over the support and fasten it using the existing screw locations. No additional modification to the main chassis is required beyond aligning with the resin brace mounting points.

In tuning terms, adding this plate increases rear rigidity and shifts handling characteristics toward a firmer rear. Drivers use the brace to tweak traction and yaw without changing suspension geometry or drivetrain components. This is a dedicated RC component for model setups.
