Using the support blocks is super easy. Simply remove the tires from your buggy and using flat HUDY Set-up Board #108202 put the car chassis on the support blocks; place the front support block below the servo saver, and place the rear support block below the rear suspension mounting. Using the #107711 HUDY Chassis Droop Gauge with elevated scales, measure the droop under the wheel Axle hex. Use the downstop screws to alter the suspension droop on each side of the car; the shocks should extend out far enough that they do not limit the suspension arm movement. Ensuring equal and proper suspension droop will allow the car to achieve a proper traction level and weight transfer depending on track conditions. Please refer to your's car set-up book to learn more about how to adjust the droop of your buggy.
