I had my black NSX's windows tinted 35%-light-passage all the way around this spring. I'm happy with the cooler interior but not so much with the look.
I intend to have the side window tints removed and redone in a lighter tint, probably 50% or more. 35% is just too dark and you lose some of the lines that make an NSX distinctive. The pillars are part of the look and when they blend in with the windows, something is lost.
You also might want to consider a very very very light tint (e.g. 85-90%) on the windshield to reduce UV and some heat. Chances are this is illegal where you live, though, so you'd be taking a chance.
