There was an article about this in SCC. Just TRY and figure out your local laws...it won't matter in the end. Some of the officers they talked to said the bottom of the car could not be lower than the center of the wheel. Too bad almost every vehicle comes like this bone stock. Another one is that the vehicle is too low if the bottom of the vehicle is below the bottom of the wheel. Another is that the headlights and foglights must be x inches above the ground. I'm sure this varies by locale.
