for those of you who have gotten tinted windows on the M3, question: opening the doors will move the windows up and down a smidge, does that affect the tint installation? I believe you can't roll the windows down after install for a few days, right? Thanks!
Not if the tint installers are used to dealing with cars that do this (almost all luxury cars have this feature). I asked my tint shop how they did it and they showed me a really simple way... they just used a wooden dowel to push on the door latch so the door thought it was closed and rolled up the window. After that they could get the entire glass area. No rolling down of windows for a few days, I just left my car outside in the sun after getting it tinted and it was fine 24 hours later.
