The Factory Pro O-3CP008 one-piece upper deck is a graphite aftermarket top plate for the 3racing Cero FWD Ultra 2.0 touring chassis. As an upgrade it modifies upper-structure stiffness and helps redistribute flex compared with the stock top plate.
This deck is made specifically for the stated chassis and matches the Cero FWD Ultra 2.0 mounting points. Installation usually reuses the kit's existing mounting hardware and internal items like the servo, ESC, and motor, but confirm screw lengths and standoffs before final assembly.
In tuning terms the graphite deck shifts rigidity to the top plane, influencing roll and mid-corner stability on FWD cars. It is intended as a chassis tuning option for track use or practice when subtle changes to torsional response and steering are desired.
This upper deck is a straightforward way to alter chassis stiffness for FWD setup work without changing the lower chassis; confirm fit and hardware before competitive runs.
