A long extension and socket will fit as well, though the bottom one you will need a 1/4"

Note: When adjusting the coupe window pretensioner, the nut it is spinning inside is plastic. Do not overtighten it or you will strip it, and that's a bad day. If this happens, you either need a new window regulator, or you need to take apart the door panel, unscrew the entire adjustment mechanism, shove a 14mm hex wrench in there, pretension the window to the level you'd like, then put it all back together. That's what I had to do
