You may want to look at the description for the GT500 rotors as it is very misleading. "2007 - 2012 5.4L, Shelby GT500, Shelby GT500KR (Front Only) Cross-Drilled and Slotted or Dimpled and Slotted Brake Rotors"
I don't try to miss lead people, but I see your point. So I made the change below. Is that better?
2007 - 2012 5.4L, Shelby GT500, Shelby GT500KR (Front Only) Cross-Drilled and Slotted. (Dimpled and Slotted Brake Rotors - add $43.08)
