5 Once the string is confirmed to be parallel to the rear wheel you can move to the front wheel on the same side. If your measurements on both sides of the front wheel are the same, then the wheel is in alignment (pointed in the same direction) with the rear wheel. If the distance from the string to the front of the wheel is longer than the same measurement at the rear of the wheel, then that wheel is toed in. If both measurements are larger than the same measurements to the string at the rear wheel, then the front wheel is sitting inside the track of the rear wheel which can cause handling issues you should be aware of. Obviously, if the measurements are smaller, the opposite is happening. Generally, moving the right front wheel out (increasing the track by using a wheel with a different offset or a wheel spacer) will help tighten the car up because it changes the crossweight.
