Race-Oriented Graphite Deck for Sakura D5MR

The 3Racing Sakura D5MR SAK-D5640 graphite upper deck is specified to increase torsional rigidity where setup precision matters most. Intended for drivers who adjust chassis flex to tune handling, this deck supplies a more stable reference for suspension and roll control work.

Technical Benefits for Tuning

Using a graphite upper deck reduces mid-chassis compliance, which helps establish consistent roll centres and predictable weight transfer. This stability lets you evaluate spring rates and damping changes without masking effects from a flexible top deck.

Installation Considerations for Competitive Use

The SAK-D5640 conforms to the Sakura D5MR mounting layout to simplify replacement. For optimal race setups, verify battery and electronics positioning after fitment and recheck baseline geometry before track testing.

How does a stiffer upper deck affect corner balance?

A stiffer deck reduces chassis-induced understeer or oversteer variability, allowing suspension adjustments to more directly influence front to rear balance.

What setup changes are recommended after fitting the SAK-D5640?

Start by reassessing roll stiffness and damper settings; small reductions in anti-roll bar rate or softer droop can complement the added deck stiffness.

Is this deck suitable for tuning across different track surfaces?

Yes, a consistent chassis reference helps when transferring setup changes between high and low grip tracks, though final spring and damper choices will still depend on surface conditions.
