i got mine done at special-T-tinting. it was like 150-60, not sure because i had two cars done at once, and yes 35% is the legal limit. but between the hawaii peeps, who actually follows the law, especially for tint. i was going to go 20% all around but then there's a possibility of getting pulled over at night, especially when you had a few drinks (not drunk). so i decided to get 20% sides and 35% in the rear. that way, when there's a cop behind you, your tint looks legal . i have friends who have 5% sides and 35% rear and they havent gotten pulled over either. and if you do get pulled over, just roll your windows down in respect to the cop because that is what they care about the most. and btw, you cant even tell that it's 2 shades of tint...it just dark and people cant really seen in.
