Your SVT tire size is 205/55/16. His is 205/50/16, meaning that your speedometer will be -3.2% off ( Tire size calculator ) Confirm somewhere that the offset is very close to 42mm (stock SVT). My wheels have 38mm offset and they rubbed until I "persuaded" the fenders out of the way. Your bolt pattern on SVT is 4x108 (4 bolts, 108 degrees). Confirm that the focus wheels are the same. Heck, call Tire Rack and ask as if you were going to buy.
