The 3Racing Cero Separate Graphite Upper Deck, SAK-CS130/GA, is aimed at competitors who want refined torsional control and repeatable handling. Its graphite construction improves top-deck rigidity to reduce variable flex under high load.
Graphite offers a tuned balance between stiffness and mass. When used as the upper deck it shifts chassis behaviour toward sharper steering response and more consistent mid-corner balance, which assists setup testing and data-driven tuning.
Fitment to the Cero Sport platform is straightforward, using existing mounting points. Consider adjusting anti-roll bars and shock tuning after installation to exploit the altered chassis flex characteristics.
