Thank you semtex for the pictures and others for your input.
I'm leaning more toward the 40%. I remember always having that weird feeling when I was next to a cop with my 20% in the 350Z. My point is, why give the cop a reason to pull over when I can just get a lighter tint. I am still debating about 30% as well. It'll give me better heat protection in the summer. I guess you guys have to check tomorrow and find out what % I got!
