My mods on my 2013 were done in this order:
1. GAS - 3dCarbon front splittler, CS side scroops, GT500 rear wing, Roush 20" Painted-Hyper Black rims, Falken Azenis tires, V6 side mirrors
2. American Muscle - GT500 axle back, SCT iTSX
3. Les Schwab -
Eibach Pro Kit and adjustable
panhard bar
I won the car from MustangCustomizer.com, and my prize was the car built by GAS nearly exactly how I built it online. I didn't choose the Falkens, but they seem like high quality tires. All looks and aesthetics. I didn't get to choose any of the interior options, including the choice between auto and manual, and Ford selected the auto on my behalf.
I went with the GT500 axle back set to give a louder rumble on WOT but no drone and still quiet idle, and I preferred filling in the rear valence gaps with 4" exhaust tips as opposed to the stock 3" tips. I obtained the SCT iTSX so that I can change the way the auto select-shift responds, since from the factory it is ridiculously slow. BAMA custom tune FTW.
I went with the Eibach Pro Kit and adjustable
panhard bar per the recommendations of
04sleeper. His stance was sweet, so I stole the look and ran with it. Purely aesthetic decision as the stock ride was quite fine.
That's all the mods I intend to do with this vehicle. It's an automatic and it is a timeless and priceless sentimental car that will stay in my family hopefully for generations to come, so not looking to mod it any further. Mustangs come and Mustangs go, so I expect another one to come in my future that I will go mod crazy on.
