The Factory Pro O-3CP008 one-piece upper deck is an aftermarket graphite top plate developed for the 3racing Cero FWD Ultra 2.0 touring chassis. Fitted as a hop-up, it alters upper-structure stiffness and shifts flex distribution relative to the standard kit top plate.
The component is designed specifically for the listed chassis and aligns with the Cero FWD Ultra 2.0 mounting layout. Installation generally reuses the kit's original mounting hardware and internal components such as servo, ESC, and motor, but always confirm screw lengths and stand-offs before you complete assembly.
From a tuning viewpoint the graphite one-piece deck increases rigidity at the top plane, affecting roll characteristics and mid-corner stability on FWD cars. It is aimed at drivers seeking a controlled chassis-level tuning option for circuit work or practice sessions.
Select this upper deck when you want a clean top-plane stiffness upgrade for FWD tuning while leaving the lower chassis geometry unchanged; verify fit and fasteners before competitive running.
