I think he is asking what state you are in because in my state the tint laws are strict, and they pull you and give you a ticket for breaking it. Heres a pic of my rx, with 35% tint all around. I would rather have black all around but the tint is in the glass, so you'd have to have all your glass replaced, BIG $$$$$.

 

i am inlouisiana here over 40% is illegal, but who cares i would rather look good and have privacy, as for swapping out the glass i didnt and it came out pretty black i think
