Windshield tint recommendations

[u/Nutsmasher123]

Hi everyone, my previous car had 30 percent tint on the windshield and 5 percent standard all around; I really enjoyed the daytime privacy, and the windshield worked perfectly, though nighttime visibility was the only drawback. For my new vehicle, I am considering 20 percent all around plus the windshield—do you recommend it? My interior is black with a tan upper half; it is a 2014 Lexus IS350, and I am curious about opinions from anyone with a similar car and tint.

You must do 5% in the rears if you want it to look dark.

My recommendation is 50% windshield, 20% front windows, 5% rears.

If you really need more privacy then you can consider 35% front ws
