27% on the fronts in SC......
I paid someone to do the wifes and was told only 35%....

But they also said the rear could be as dark and wanted, so I added 5% to the stock 20% and that can only be 27% also....

Oh well, after 3.5 years, not been pulled over yet in any state it's travelled though.
Did do 20% on the front of the truck and the HHR and additional 20% to all rear windows. Have not been pulled over for tint yet.
