Measuring camber at home with the iPhone

Shortly after buying an Apple iPhone, I found an application called Clinometer - it's a level and slope finder available from the iTunes Store for a reasonable 99 cents. It uses the phone's built-in accelerometers to measure angle with amazing accuracy. Useful for hanging pictures on your wall, making sure your new plasma TV isn't crooked, and most importantly, making sure you are getting the most out of your tires while autocrossing and on the track.

Step 1 was to find a straight block of wood that is cut to touch the top and bottom lip of the wheel:

Step 2 is to put this block of wood on the garage floor and go through the simple calibration procedure in the application. I could calibrate it from multiple directions in order to measure my camber relative to gravity.. but since the car in on the ground, I want to measure it relative to the garage floor only.

Finally, I can place it against the block of wood pressed against my wheel:
