The after looks killer! when I get new weatherstripping someday, I'll have mine tinted. I thought about doing 5% but 20% looks realy good and I'm sure at night time it's a much better choice. To stay legal with FL tint laws my daily driver Explorer has 28% front with the factory 15-20% rear. Looks alright, kinda wish it was darker like yours. The shop that did mine will do darker than legal but they charge more for it, and will not warranty it.
Find out what is legal and go with that--anymore is not only against the law, but NOT safe (hence, why it is illegal). Good luck and have fun putting it in!
