can anyone tell me if this is gonna fit my 13 gt 5.0?
also does it come shipped in 2 separate pieces cause in the pics ive seen i dint this my factory chin spoiler is gonna fit with this set up.

its like 800 bucks basicly but i really like the looks of it

 

If you're taking about the extension under the stock front splitter then no it won't fit unless you drop extra on the install kit, M-16601-MBKIT, which is referenced as being needed by GT's. You could however get the install kit and then make your own splitter for tons cheaper. http://bossmustangsonline.com/index.php?topic=6015.0 is a thread describing how to make your own.
