The 3Racing Sakura D4 FPR Upper Deck is engineered to tighten the chassis response for drivers who tune setups. Using Fiber Reinforced Plastic, the deck increases structural integrity across the Sakura D4 platform while maintaining a low mass that supports agile handling. This component is suitable for drivers refining steering response and mid-corner stability.
FPR provides a consistent stiffness characteristic that helps make setup changes more predictable. When combined with suspension damping and toe adjustments, the SAK-D418 can assist in achieving repeatable drift lines and consistent tyre load distribution.
The SAK-D418 is designed for direct fitment to standard Sakura D4 mounting points. Use correct-length fasteners and verify alignment before final torqueing to ensure the deck contributes the intended rigidity without inducing chassis twist from uneven mounting.
