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

Aftermarket main plate for Cero Ultra 2.0

This Factory Pro O-3CP009 graphite main chassis is a direct-fit aftermarket replacement made for the 3racing Cero FWD Ultra 2.0 platform. Machined graphite at 2.25mm nominal thickness gives a consistent stiffness baseline for front-wheel-drive touring car setups, letting tuners refine handling with stack, suspension and ballast rather than compensating for an unpredictable chassis.

Installation focuses on retaining the original geometry: the plate lines up with the Cero Ultra 2.0 mounting pattern and uses the stock fixing points for suspension, motor mount and electronics. When swapping the main plate, check motor and servo clearances, confirm screw lengths are correct for secure clamping, and torque fasteners to the values in your kit manual to avoid concentrated stress on the graphite surface.

In practice this plate helps control flex under throttle and during cornering. Fit it as part of a step-by-step setup change: re-establish ride height, anti-roll and spring rates after installation and test on both high and low bite surfaces to dial in the handling balance.

Choose this Factory Pro main chassis when you want a stable graphite platform for tuning front-wheel-drive Cero Ultra 2.0 rigs, and always confirm fit and clearances before final assembly.
