You've got the wrong idea about how offset works, unfortunately.

Offset is the distance from the centerline of the wheel to the flat area (plane) of the mounting surface. Thus, +/- 0 offset is a wheel whose mounting surface is at the center of the wheel. So, the higher the number, the more the wheel sits in towards the center of the vehicle.

At 55mm, the factory Ti wheels are considered to have a fairly high offset. Your wheels, at 35mm, definitely won't fit. With the spacers, the offset will drop to 10mm, since it brings the mounting surface closer to the center of the wheel. You're looking at a setup that absolutely won't fit on the Focus.

Here's a good calculator that will explain things in a more concise fashion:
