DewwutAccording to Bonnie & Clyde, you can run 50%
70 is what the windshield is from the factory normally. Anything aftermarket that's lighter than 50 is just a waste of money.I was incorrect, "Yeah 70% is completely legal but probably recommend doing 80 just because that 70% believe you kind of a glare during the day"
