I'm thinking about going with 10" 214's in the front and rear instead of the staggared setup with 10" in the front and 11" in the rear to get a little better traction in the snow (using Yokahama Parada Spec-X tires). Has anyone done this and does anyone know how much spacer I need in the rear to bring the wheel out the same width as the 11" wheels?

Also, does anyone know the part number for the wheel flares?
