well you can have the tint on the back of your rear windows & rear sides can be as dark as you want, you can make them limo tint or whatever color you want. the only hard part is your two front(passenger and driver side) windows, I have 15% visibility which is dark, you can't see me at night unless you have a street light pointing at me. In the day time you can see but not a from a distance. Obviously its illegal tint, but i don't care. I have had my tint for about 1.5 yr's and i haven't been stopped or given a ticket at all. My friends have, he got jacked 3 times in Irvine, those guy are bastards.

if that webpages info is correct than your legal limit for tint than you can only do 88% and up which is barely anything. I don't like having darker tint in the back and light in the front. I rather have it even all around. im sure you can go darker than 88% without getting pulled over.
