I currently have 3% on my side windows, 30% on my windshield; and 3% on my rear glass. Personally for me I have no issue seeing; however if you’re not used to driving with darker tint already I would not recommend it.
ok well now you are lying. with 3% tint you will not be able to see out at night. And more importantly noone can see inside, not even during daytime.
I do think the rear looks quite cool all black though.
