The 3Racing SAK-F103 Graphite Upper Deck is produced to align precisely with Sakura FF21 mounting points, offering a stiffer torsional platform for refined handling. The graphite construction reduces flex that can alter suspension geometry under load.
For racers and tuners, graphite provides a reliable stiffness profile while keeping mass low, which aids repeatable adjustments and predictable chassis behaviour. That makes suspension tuning more effective and consistent lap to lap.
Install the deck using correct fastener torque and confirm clearance to avoid localised stress. Pairing this plate with targeted shock and roll centre changes will reveal its full benefit in cornering stability and throttle control.
