How do you like them? Do they do a good job of getting rid of wheel hop? I am considering them b/c I can have Ford put them on when I purchase my Mustang and don't have to worry about any potential warranty issues. I spoke to dealership today and they said it would not be a problem and that they add things from FRPP catalog to many Mustangs and it will not be an issue with warranty as long as they put the parts on.
