Keep that sh!t gangsta,every car I own always had 20% or darker. If you must keep your tint do around 20% or higher and also do the windshield at about 30%-40% (This is very illegal by the way) that way you will still keep most of your privacy. To me I wouldnt lighten it up a little not to the legal limit, though. Then again some county's are just strict on tint and some arent. I don't know if its just me but that privacy is everything. You gotta love it!!
