So let me give you a little insight into what happened with mine causing me to swap them out for the Wilwoods. I ran out of pad at 17,000 miles or so. This is when I first bought the car. And when I went to get pads, nobody had any. No Dealers, no Aftermarket nothing. The other problem I had was the fronts were both wearing to the inside about 75% to 1 versus the outside. It is not suppose to do that. I found a set on Amazon out of California. That bought me another 20,000 miles. Still my local dealer did not have pads and they were backordered from Ford. So I decided to go aftermarket. I ran this up the food chain pretty high at Ford, and although they listened to what I had to say, nothing ever came of it. The other problem was Ford was releasing data to the aftermarket database company that supplies companies like ORileys Advance Auto Autozone and the like with incorrect information about what pad would fit. All of these places had the ST listed but had it matched with standard Fiesta pads, which is not correct.
