Well the problem is, just like Chrysler warranty, if it fixed under powertrain (like your's was) you dont have warranty after powertrain warranty is done. So when they offered to "goodwill" it and you pay half, you should have done it. Then you would have warranty
I had the Conti dws06 on my car, just replaced them with dws06 plus. I LOVED the regular dws06. They were amazing, dry or wet. Especially wet, I did some stupid stuff in the wet and it always stuck unless I was just ignorant with the throttle. I didnt think they were any noisier than the stock...
I am not going to do that, but thanks for playing. Go back to the GT forum. There is no reason for ford to allow flexibility, its says E15 thats flexible enough.
