For those tuning the 3Racing Cero Ultra Ver 2.0 for competitive running, the Factory Pro FP-O-3CP004 Option Main Chassis offers a stiffer, lighter platform. The 2.25mm graphite plate helps deliver more precise handling and consistency across consecutive laps.
Graphite is chosen for its high stiffness relative to weight, which reduces unwanted flex and sharpens steering feel. This material choice benefits drivers who want repeatable behaviour when adjusting suspension and steering geometry.
The FP-O-3CP004 is made to match the 3Racing Cero Ultra Ver 2.0 mounting layout so fitting is straightforward. You can retain your existing electronics and most peripheral parts, allowing a clean upgrade path without major modifications.
After fitting, check all fasteners and re-test after initial runs. Look for any signs of stress around screw holes and replace the chassis if you spot deep cracks. Regular checks will keep your setup reliable during race weekends.
