Thats the only thing I don´t like about the covers, there´s no attachment point at the turn signals. however, I have thought of doing this: where the screw holds the turn signal onto the car itself you could drill a hole into the GTS cover and use that screw for the cover as well. that would hold it down and make it look slightly better... the only problem is I don´t always keep my covers on and that would make it more of a pain to take off.
