The 3Racing SAK-C153A rear graphite body plate is produced to interface with the Cero Ultra 2.0 chassis. As a graphite upgrade component, it is intended to increase rear section rigidity while preserving a minimal mass footprint to support sharper handling responses during competitive use.
Graphite provides a controlled increase in stiffness, reducing variable flex that can complicate setup work. Fitting this plate stabilises the rear platform and makes vehicle behaviour more predictable when adjusting damping and roll balance.
The SAK-C153A aligns with the Cero Ultra 2.0 mounting scheme and is intended for direct installation using standard fasteners. After installation, verify alignment and torque values and re-evaluate spring and damper settings to exploit the change in chassis stiffness.
