I’ve never had any problems with any of my cars tinted, but I also don’t give cops a reason to pull me over in the first place. My advice is tint what you feel comfortable with. Remember you can always put your windows down when pulled over.
My sapphire blue Reatta is finally tinted all the way around except for the front windshield. The rear windshield is also tinted in all one piece so it is possible… but difficult.
On eBay they are selling unpainted Alero wings. Hope this helps
