The 3Racing SAK-CS165/GA Graphite Upper Deck is specified for competitive use on the Cero Sport chassis to reduce unwanted flex and sharpen handling response. Made from high quality graphite, the component keeps mass low while improving torsional rigidity where it impacts cornering performance.
Adding the 3Racing SAK-CS165/GA will alter chassis stiffness, so expect changes to balance and transient behaviour. Tuners should evaluate roll centre and shock settings after fitting to dial in optimal handling for lap consistency.
