A method and apparatus are disclosed that assist a user in performing proper setup of a vehicle suspension. A user may utilize a device equipped with an image sensor to assist the user in proper setup of a vehicle suspension. The device executes an application that prompts the user for input and instructs the user to perform a number of steps for adjusting the suspension components. In one embodiment, the application does not communicate with sensors on the vehicle. In another embodiment, the application may communicate with various sensors located on the vehicle to provide feedback to the device during the setup routine. In one embodiment, the device may analyze a digital image of a suspension component to provide feedback about a physical characteristic of the component.
