My buddy has limo all the way around on his souped up mustang and has received a ticket before, and so have a couple of people I know with imports. However, I drive a newer truck with limo tint, and so does another guy I know with a F350 Diesel, and we've never been pulled over. I think it has to do with how big of a punk you look like. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
When I drove fixed up racing type cars I would never put illegal tint on them, I would have surely got ticketed, but now that I have a truck on 22's, I think it's required to have dark tint. No problems yet, but I can't see worth a shit at night (except out the side windows, my fronts are limo, back windows are factory tint + limo, rear window is factory tint + 20% + limo, lol), I suggest getting a rear view camera, which I plan on getting soon before I run over some kiddies or something...
Another cool thing to look into if you're into security is bullet proof tint, they sell it here at about triple the cost of normal tint.
