The 3RACING SAK-A565 1.5mm graphite upper deck stiffener is a purpose-built component to raise torsional stiffness on the Sakura Advance 20M chassis. By limiting chassis twist, the plate helps the suspension work more predictably and refines front-end feel during high-speed transitions.
Graphite delivers high specific stiffness with minimal mass, making the SAK-A565 an efficient way to shift tuning bias without significant weight gain. Expect reduced mid-corner flex and clearer feedback to assist setup decisions on shocks and roll bars.
Install the plate using proper thread engagement and even torque across mounting points to avoid preload. After fitting, verify corner weighting and assess handling changes at different throttle loads to optimise shock and anti-roll bar settings.
