This is the Fioroni Ultra Racing Series Option Team 1/8 Off Road Tire Balancer.
This aggressive, yet appealing aluminum tire balancer is one of the nicest available. Featuring a graduated scale, it gives you reference points that allow you to place the balancing putty exactly where it needs to go.
These days, balanced tires are critical in order to achieve peak performance, even at the club race level. Balanced tires allow the vehicle to operate with less vibration which creates a vehicle that is easier to drive and jump. Not only does a vehicle with balanced tires jump better, rotating drive train parts like axle bearings and drive shafts will show less wear over a long period of time.
