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

Main chassis for Cero Ultra 2.0

This Factory Pro O-3CP009 graphite main chassis is a direct-fit aftermarket replacement produced for the 3racing Cero FWD Ultra 2.0 platform. Machined graphite at 2.25mm nominal thickness provides a predictable baseline stiffness for front-wheel-drive touring car setups, letting tuners adjust handling through stack, suspension and weight distribution rather than by compensating for chassis unpredictability.

Fitment and installation are focused on preserving the stock geometry: the chassis aligns with the Cero Ultra 2.0 mounting pattern and uses the existing mounting locations for suspension, motor mount and electronics. When swapping the main plate, verify clearance for the motor and servo, confirm screw lengths match the original hardware, and torque fasteners to the values recommended by your kit manual to avoid localized stress on the graphite surface.

In practice this chassis is useful when you want a firmer platform to reduce flex under throttle and corner load. Use it as part of a systematic setup change: adjust ride height, anti-roll, and spring rates after installing the plate and evaluate handling on both high and low bite track surfaces to find the intended balance.

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