The 3Racing SAK-C130A Cero Ultra Graphite Upper Deck is a performance-focused upgrade tailored to the Cero Ultra platform. Manufactured from high-modulus graphite, the top deck increases torsional rigidity to give technicians and drivers a firmer baseline for suspension and shock tuning.
Graphite delivers a high stiffness-to-mass ratio that reduces unpredictable chassis flex and improves the reproducibility of setup changes. Using the 3Racing deck refines transient responses, making chassis adjustments more linear and predictable during lap-by-lap tuning.
Engineered to align with Cero Ultra mounting geometry, the 3Racing SAK-C130A installs without chassis modification. For optimal performance, verify fastener torque and observe how the stiffer platform affects roll centre and anti-squat characteristics so spring and damper settings can be rebalanced.
