I have an 05 saleen focus...it rides incredibly rough. My buddy over in AL has one too. We both have less than 40k miles on our cars. He thought his shocks were blown.
It is what it is, the car rides really rough. This 'noise' that you are talking about....kind of hard to diagnose from what you said. could be your wheel hitting your inner fender, wheel rub, bad bushing, all kinds of different things.
