This Factory Pro O-3CP008 one-piece upper deck is an aftermarket graphite top plate made for the 3racing Cero FWD Ultra 2.0 RC touring chassis. As an RC-scale hop-up, it changes the upper-structure stiffness and helps redistribute flex characteristics compared with the original kit top plate.
Fitment is specific to the listed chassis; the deck is shaped to match the mounting points and spacing used on the Cero FWD Ultra 2.0. Installation normally reuses the kit's existing mounting hardware and internal components such as servo, ESC, and motor without modification, but confirm screw lengths and stand-offs before final assembly.
In tuning terms the graphite one-piece deck is used to bias chassis rigidity toward the top plane, influencing roll and mid-corner stability for FWD setups. It is intended as a chassis-level tuning option for track or practice use where small changes to torsional response and steering feel are required.
Use this upper deck when you need a straightforward chassis stiffness option for FWD tuning without altering lower chassis geometry; verify fit and hardware before track use.
