dude 70% is a waste of money.. honestly, its as light as stock windows. Even stock windows aren't 100%... I was hesitant, but i got 32% fronts, 6% sunvisor on the windshield, and 12% on the backs. 32% is even light enough to see the person's face/outline but not TOO light. Blocks sun and it's great. 32-35 is the best for the fronts.. cops saw it and did nothing.. i mean, honestly, the cops gotta be a SERIOUS dick if he gets out of his way to turn on his lights, stop you and give you a stupid fix it ticket. (unless it's a hazardous issue like no brake lights)... 32%-35% ... get it, you won't regret it. LOL i was so paranoid the first couple days after i got the tint because i couldn't roll down the windows for 2-3 days.. so i HAD to just keep it up. My heart jumped everytime a cop passed, but nothing happened. I don't even roll down my windows that much .. If you're worried, (especially at night), just open the cover of the sunroof or OPEN the sunroof and it'll make your tint look lighter. Btw, i live in the OC and OC cops are known to crack down on Modders and what not.
