New from HPI Racing are Setup Wheels in brilliant purple anodized aluminum. Racers use setup wheels to help get the exact suspension geometry adjustments at the racetrack, and to help prevent flat-spotting their race tires while working on the car. These official factory HPI parts feature a lightweight design that also allows them to be stacked while not on the car, saving valuable pit box space while traveling to races. Rubber O-rings are included that grip the surface of setup boards to prevent the car from sliding while making adjustments. These are "must-have" items for serious racers, and they look great too!
