i just did mine today, i went to auto glass shop and he was about to start removing the whole glass.
actualy lot of auto glass shops refused to do it judt because they worried of damaging the glass.
thanks to you guys for all the information that you have provided, i explained to the tech person how to do it. at first i was worried if the glass brakes, but it was very easy it took less than 20mns.
they also install for me AC schnitzer spoiler(OEM ofcourse), splash gards front (R,L) all that for $80.
yesterday i installeed M5 mirrors (OEM of course) what a difference, and i installed door handels lights. i will take some pictures soon.
again i just want to say thank you all for sharing your knoowldge with all of us.
