NH seems to have some of the worst laws for cars. I dropped off my car in Mass to get tint done. I asked for 50% all around and I guess they didn't hear me right...picked it up with 15% all around. Got a deduction off the price and to be honest I am kind of glad it happened. The NH cops give me a hard time but that's the price you pay. Honestly Ben, I would do EL headers (Tomei or maybe KillerBee) tint and then a prova D or GT spec steering wheel.
