All my cars have all the windows tinted and yes it is not legal in Cali to tint the sides unless it is behind the driver's window. It keeps it cooler in the car and gives it a whole new look. I have not had an issue with tinted windows in all the years I have had them.yea its nice and dark inside now thats not legal (at least on the sides) so we will see how long it lasts. its a fix it ticket only so no biggie if a cop decides to be a prick to me.
