Boss front splitter installed.

i'm 95% positive that this is a 'yes'. i remember reading that the mustang crew decided early on in the '10 development to add splitter mounting points to the factory piece for ease of use with the FR500 cars(the boss LS splitter is the same as the FR500 piece).

You probably can do it, but you're going to have a huge gap. When I installed mine, i had to drill into the valence and the bumper cover to attach the splitter. Plus the splitter I have is the regular splitter, not the lacuna seca splitter.
