I did the same with my Mustang but kept 15% all the way.
Yours looks great!
When I lived in MI I had either 35% or 20% on all my cars. Never once had a problem.Looks great, though I'm not a fan of the W/S band myself.
The only side window tint allowed here w/o a medical Rx is the top 4" of the window. I run 35% all around, have never had a second glance from an officer, and was stopped twice with a previous car with the same tint, they never said boo.
