The 3Racing SAK-D5603 is a 197mm graphite rear suspension plate developed to provide a stiffer mounting platform for the Sakura D5 Pro chassis. Its reduced mass and elevated rigidity support sharper transient response and repeatable handling during setup work.
Graphite delivers a targeted increase in torsional stiffness with minimal weight gain, allowing tuners to change the chassis flex pattern without affecting centre-of-gravity significantly. The SAK-D5603 supports precise adjustments to roll and traction characteristics when paired with suspension fine tuning.
Manufactured to align with Sakura D5 Pro mounting geometry, the plate installs as a direct replacement. For competition use, confirm all fasteners are torque checked and re-evaluate shock damping and sway settings to capitalise on the altered rear stiffness.
