I wouldnt get 5 anywhere, you cant see anything at night.. In AL it is illegal to have tint ANYWHERE on a car unless it is the rear window and you cant have in on an SUV accept the back window and the back gladd above the quarter panel, you cant have it where there are any windows.. Accept the normal 35%
I got 20 all the way around but it kinda sucks because on my mounty I have factory tint and the back is that reflective tint (mirror) far away the front looks darker and up close the back looks darker. It sucks, but I like the 20 all the way around. 5 is to risky, thats just telling a cop you dont care about the laws. And honestly getting 5 is just iggnorant, you will pay WAY more in the future, I have not had problems out of the 20
