Hi Buddy! If your vehicle is registered in NC: The 2 front doors are restricted on trucks, vans, and SUVs. Those 2 windows have to meter out no darker than a 35% NET in order to pass inspection. The entire rear half does not have a limitation, so all rear windows can be as dark as you would like. If you have a sedan or coupe, ALL of your windows are restricted so ALL of your doors and back glass have to meter out @ NC's 35% NET.
They did a super job on my SL500
