The 3RACING SAK-D543 wheel hex extension is intended for setup-minded racers seeking fine control over wheel track width. Precise spacing adjustments can influence weight transfer and turn-in response during high speed cornering.
Designed to complement Sakura D5 race setups, the extension lets you make measured changes that affect handling balance and transient response. Use it alongside changes to suspension and roll stiffness to refine overall chassis behaviour.
This extension is matched to SAK-D534 and SAK-D545 chassis variants to ensure correct alignment and predictable tuning outcomes. It is a practical choice for racers who iterate setups between sessions.
