Setup-oriented graphite hub for competitive tuning

The 3RACING SAK-U321 Graphite Composite Rear Hub is produced for the Sakura Ultimate chassis to support precise setup adjustments. The built-in 2-degree toe offers a predictable change in rear geometry useful when optimising balance, while the graphite composite keeps component mass low without sacrificing stiffness needed for consistent feedback.

Tuning benefits and fitment notes

From a setup perspective, the SAK-U321 helps reduce rear understeer at turn-in and improves line consistency through apexes. Fitment aligns with Sakura Ultimate rear mount points; when integrating this hub into a race setup, re-check toe, diff preload and shock rates to harmonise overall handling.

Adjust rear shock damping and differential preload in small increments after fitting. The 2-degree toe works best when combined with small camber and anti-roll bar tweaks to maintain front to rear balance.
A change in toe can shift contact patterns slightly. Monitor tyre wear after installation and adjust toe or camber if uneven wear is observed.
Ensure fasteners are torqued to spec and check clearances with suspension links. Verify alignment on a setup stand to confirm the intended 2-degree effect before track running.
