I expect to take delivery of my grey 85D in a couple weeks, entered production 2 days ago. From the picture of My Tesla page, it does not appear it comes with factory window tint. Is this correct? To make it road trip worthy, I plan to tint it all around and be legal in California, with 3M Crystalline: windshield CR90, front side CR70, back side and rear CR40. To take advantage of no limit in California for back side and rear windows, I am thinking of going extreme all the way down to 5 (3M Color Stable CS5). Would this too low and would cause certain unexpected problems, such as difficulty driving in the night? Should I stay around 35-40 range just to be safe?
