You have an ST. Not an Edge Sport. Ford has already done everything for you. 20 HP over the Sport. 10% stiffer in the front, 20 % in the back. Monotube shocks instead of twin tube. You have sport mode if you feel like you need it, even though 90% you don't. Also, you can double tap the ESC button and put the advancetrac into sport mode. A hidden gem with the ST
The ST is everything the Sport wishes it could be. Don't change anything. Mine does have the Performance Wheel and Brake package which makes all the difference in the world. The Pirelli Pzeros turn it into a true performance SUV. .
Trust me, you don't need all that tuning crap. You already have it. You have an ST
