5% all around, 35% windshield for me. I like the 35% on the windshield though. At night, you cannot see through, but it's not too dark to where you can't see ****. Even 20% would be hard for me at times. . .
Thinking about tinted headlights since that would look badass with the tinted windshield.
I have double up 5% all around on my car, and I double tint strip half-way down my front windshield....and I can see fine at night.......If I need to see better I press a button and my window goes down, no ****.
