The Factory Pro FP-O-3CKP21 main chassis is an aftermarket graphite replacement made for the 3racing Cero FWD Sport platform. Machined to 2.25mm thickness, this graphite plate acts as the central structural member on a 1/10 scale FWD car and is intended for track and practice use by hobby racers.
Install this plate as a direct-replacement to restore baseline rigidity or to change the car's flex response. It influences suspension behaviour, weight bias and body mount positions; fitters should confirm screw lengths, spacer positions and clearance for servo arms and steering linkages during assembly.
This Factory Pro graphite main chassis suits builders who need a straight swap or who want to tune chassis stiffness on a 3racing Cero FWD Sport. Reuse your existing mounting hardware where possible and recheck toe, ride height and steering centring after installation.
