I'm planning on tinting my windows soon. I'm going to go as dark as possible in the back and am not sure what would be good for the front. I don't want to go so dark that I have to worry about the cops every time I see them. I live in california and law says you have to have 70% coming in the front. Would 50% make a noticebale differnece and not attract too much attention from the cops? If 50% isn't really notceable what would look good but not draw too much attention. Sorry if this was already answered, but their are too many tint posts and I don't feel like looking through all of them.
