I found out that as long as you look nice, don't tint your window 100%, and make the front window less% than rear..cops leave you alone...
I think the % is really how you want your car to look like. Choose a good brand of film is the key.
i just cant stand the uneven look, the way out of the factory with only rear tints. that bothers me. first week getting the car i got it tinted.
