3racing Cero FWD Ultra 2.0 Replacement Main Chassis Graphite 2.25 - Factory Pro O-3CP009  [FP-O-3CP009]

Main plate upgrade for Cero Ultra 2.0

The Factory Pro O-3CP009 graphite main chassis is a direct-fit aftermarket upgrade for the 3racing Cero FWD Ultra 2.0. With a machined 2.25mm graphite construction, it provides predictable baseline stiffness suited to front-wheel-drive touring car tuning, allowing setup work to focus on stack, suspension and ballast adjustments instead of compensating for chassis compliance.

Fitment is intended to preserve stock dimensions: the plate matches the Cero Ultra 2.0 mounting scheme and uses the same mounting points for suspension components, motor mount and electronics. When replacing the main chassis, inspect motor and servo clearances, ensure screw lengths and types are appropriate, and torque fasteners to the kit recommended values to prevent localised loading on the graphite.

Teams and hobbyists use this chassis to limit flex under power and corner loads. Install it as part of a methodical setup routine: recheck ride height, anti-roll and spring rates after fitting and trial the car on different surface grip levels to find the desired handling balance.

Use the Factory Pro main chassis when you want a stable graphite base for tuning front-wheel-drive Cero Ultra 2.0 cars, and always verify fit and clearances before you run the car.
