Although the product is really useful for determining suspension settings, it becomes impossible to do anything about it effectively. Example: A customer has a Ford Mustang, specifically a GT350, and while the product can tell you which toe you have, it doesn't have the ability to get under the car to adjust your settings when your car is on the ground . Now if you decide to put your car on jack stands to adjust toe or camber. You don't have the ability to mount a device on a rim or tire and then set it up and then effectively tune it. To be honest I would have returned it but ended up on a business trip and missed the return window.
