We have Dynamometers at our retail location in Flint, to provide you with accurate and reliable Speed Checks for your car or truck.
Speed Checks are highly recommended if you have recently changed your tire sizes, and necessary if you have changed the trans-mission or gearing in your vehicle, to determine or verify the accuracy of your speedometer or odometer.
Come to Specmo Auto Sound & Speed,"The Source" where local police departments have their own vehicles calibrated!
Upon completion of your Speed Check, Specmo will provide to you a"Certificate of Accuracy".
