What exhaust do you have and what color is the car? WRXs tend to attract attention. I think that tint doesn’t stand out on black cars like it does on lighter colored cars.
I would however keep all 4 windows down when going through an area where you think you are likely to be hassled.
I believe the law allows 70% or something, which is factory on most new cars, so basically, no aftermarket tint whatsoever.
