The offset is WAY off - so if you like replacing wheel bearings often, go for it. Otherwise, BUY THE CORRECT WHEELS FOR THE CAR!
Anyone that says there aren't enough wheels options for the Contour are talking sh!t - because of the Focus which uses the same bolt pattern and offset, we have a LOT of wheel options avaible to us. Just search for Focus wheels, rather than "contour" wheels and you will probably find more as not all wheel retailers are fully aware that we share the same wheel specs, and this is true for some CEGer newbies too.
