60MM spacers will NOT work on a Crossfire. I have never heard of anyone going bigger than 20MM on the back. I have 15MM on the back and 5MM on the front. This setup puts the tires flush with the outer fender well. 60MM should put the tires about 1 3/4 inches out past the fender. You must remeber that the offset for a Crossfire is not the same as a Z.

Also, 60MM spacers are not safe, and would be murder on the wheel bearings.

Here is what 15MM looks like of the rear:

As you can see, 5MM on the front does not leave any additional room.
