for daily use, the uprated EU suspension is perfect. Not too stiff for terrible US roads, but stable enough for some spirited driving. I need to get out and autocross it to learn more about the suspension.
The biggest thing the Fiesta needs is a better shifter, something shorter and with more feel. Most of the time I have a laundry list of things to change on a car, but I am starting to struggle finding things on the Fiesta. If the US car gets soft suspension, then it will need somebody (BAT?) to bring over the proper EU performance suspension. I am even starting to think a turbo is not needed because the car is great for daily use in the city. On a road course, then it is a different story.
