I haven't quite gotten the tint yet on my front windows but for the rear quarter windows and the rear window hatch, I just purchased the sunshade screens that match the rear passenger window screens and it makes a big difference. It makes the X5 looked tinted. Maybe one of these days I'll actually get my front windows tinted to 35%.
