The 3Racing 4mm Thick Wheel Adapter is aimed at racers and tuners who need a repeatable, low-slosh wheel-to-axle connection. It provides a compact, stiff interface that helps maintain wheel concentricity during acceleration and lateral loads.
When fitted as part of a race setup, the 3Racing adapter reduces variables caused by wheel shift and runout. That stability makes suspension and steering changes more predictable, improving the effectiveness of incremental tuning adjustments.
