yup the arches are entirely different. Dan, you can buy the RS front and rear fenders, in fact, if you want to put the 18x8" RS wheels on your focus (the ones you can get from Ford Racing here) then you'd need to have the bigger arches. Check in the Ford Racing Fast Focus Catalog, I believe they have them in there.
I WANT AN RS!!!!!!!! lol.....i love your ride...it's sweet....awesome video too...
