Had mine tinted (50% sides, 35% rear) and had a clear bra installed (bumper, partial hood, partial fenders & mirrors) for $720 total in Sherman Oaks back in the spring (
Sunshield Glass Tinting). I went there on the recommendation of a friend who had them tint his Mercedes SL 65 AMG (
Mercedes-AMG). This friend also own a 2007 Corvette and a Lamborghini Murcielago coupe so I was confident that he wouldn't recommend a fly-by-night place. They did a great job on my Z.
