The 3Racing SAK-CM105/GA Graphite Upper Deck is developed to stiffen the 210mm Cero M chassis platform, providing a predictable baseline for setup changes and improved feedback at speed.
The component uses consistent graphite layup to deliver uniform stiffness across the top deck area, which helps reduce asymmetric flex that can complicate handling trims.
Manufactured to match 3Racing Cero M mounting points, the SAK-CM105/GA enables repeatable installation and retains alignment with brace points and electronics locations for efficient race preparation.
Adding the graphite upper deck raises chassis stiffness, allowing finer tuning of springs, dampers and anti-roll characteristics; drivers will often reduce corrective inputs and observe improved mid-corner consistency.
