It couldn’t be simpler, just select your desired weight position and lower the hood. All dimensions are taken automatically by ultrasonic sensor, and the user is guided back to the chosen weight locations by means of the ‘megastick’ weight placement arm. Building on the features offered by the megaspin 200, this model is designed for those customers where only the best will do, and for high volume tyre shops where speed is paramount without compromising on accuracy. Built to last, and offering the ‘behind spoke balancing’ function featured on all megaspin models. The megaspin 400 is the perfect combination of simplicity, speed and accuracy.
