The 3Racing SAK-D5625/RE graphite upper deck is a race-focused replacement that raises torsional rigidity across the Sakura D5/D5S platform. Its stiffer mounting plane enables finer suspension tuning and more consistent handling responses under load.
By reducing chassis deformation, the SAK-D5625/RE helps maintain alignment points and camber behaviour through aggressive cornering. This makes setup changes more predictable, aiding engineers and drivers who are dialling in handling balance for lap time improvements.
Engineered for direct fitment to existing mounting points, the deck installs without modification. After fitting, expect to revisit damping and anti-roll settings to compensate for the altered flex characteristics and to optimise weight transfer during entry and exit phases.
