I have not regretted going 5% and cops havent told me shit and ive gotten two tickets. It just depends what you want it for...im young as fuk and live with my parents so yea my car is my "fun room" so my dark tint really helps with that...but other that that they are w/e, car still gets hot after a long time parked, i still see at night fine but it aint perfect...if you want dark then fuk it go dark...i guess it depends what kind of cops you got around you too.
