Race-Oriented Wheel Adapter for Sakura Ultimate

The 3Racing SAK-U329/BK wheel adapter provides a precise 5mm offset for the Sakura Ultimate platform to refine wheel positioning. Its design helps reduce lateral play and supports repeatable steering input under load, crucial for lap-by-lap consistency.

Setup and Tuning Considerations

Intended for competitive setups, this 3Racing adapter allows tuners to alter track width and scrub radius in small increments. The 5mm thickness is useful for dialling in steering response and mid-corner balance without introducing excessive unsprung mass.

Installation Workflow for Racers

Fit the 3Racing SAK-U329/BK using standard workshop tools and verify wheel nut engagement and clearance. After installation, run progressive tests to confirm improved wheel runout and adjust camber or toe as part of a full setup iteration.

How does a 5mm adapter influence scrub radius?

Adding 5mm shifts scrub and track geometry slightly outward; this can increase steering feel and alter tyre load distribution, so retune alignment as required.

What sequence should I use when testing changes?

Implement the adapter, then validate wheel runout, check tyre wear, and make incremental camber and toe adjustments while logging lap times for comparison.

Any precautions for frequent track use?

Inspect mounting faces and contact surfaces regularly, retorque fittings after heat cycles, and replace adapters showing signs of deformation to preserve consistent performance.
