Maybe I'm a total noob but what does the GSR stand for? It was on a 2013 v6 mustang.
it could be the guys initials???The stripes are like the boss and looks like a T in front, I'm getting them on thursday and just noticed the GSR. First thing Monday I'll make sure they are not putting the same letters on the sides :nono:
Thanks for your guess guys, I also google it and came up with nothing worth while...
