It´s a huge pain in the ass...
you have to take off the entire "far side" (towards the corners) of the stock BMW brackets, then fabricate an adjustment device for it, mounted on the inner side (towards the grille), and then you have to cut up the stock escort brackets on the far sides to support the grille and corner lights. Sounds like it´s easy, but it´s a huge pain in the ass because you have to work in tiny steps because once you cut too much from the stock brackets or take off the wrong piece, you´re fucked.
Then after that you have to splice the wires to the new lights, and use the common ground (stock comes with 3 leads- high, low, ground). That is a pain in the ass to do, but it´s very straightfoward.
