Attached are some pics of my Spicy so you can see the tint. My windshield strip is a lot bigger now than you see in the first pic, like 8-9 inches. Go for the tint. It looks great with it. My recommendation would be to put 35% (legal here) on the sides and 20% on the back. When I bought mine it already had 35% on the front doors and 20% the rest of the way, which is a good compromise. I've been pulled over for it b/c it looks pretty dark, but when he tested my fronts, they passed, lol. He never checked the others. I also run a large, dark windshield strip to keep the sun out of my eyes.
If you've never had really dark tint on your front windows before, I'd think twice about doing it. Back in the day I bought a Mustang GT with doubled-up limo tint all the way around. I had to roll the windows down at night just to see to turn. I got pulled over for it as well and I'll never forget the cop saying, "Son, you're 2.5% away from having cardboard over your windows..." I had to strip it and have it certified that the tint was gone. On the plus side the interior was always nice and cool and with a sunshade up I could bang my g/f in the car with people walking by on both sides. Seriously, I'd never go that dark with tint again.
