I may be picturing this wrong in my head, but by doing this you will effectively move the entire rear section of the frame back. Is this what you're thinking of? You'll have body fitment problems with this at the attachment points, through the trunk area and at the rear of the car. Not to mention the rollbar mounting points. How old is your car?

Early cars had a 90" wheelbase and did have the tire rubbing problems you are encountering. Arntz's and Butler's change on the later cars was to move the upper differential mount rearward 1" to give a 91" wheelbase and to better center the wheel in the well. Offset upper shock mounts were also used but you can get around this with spacers and a bit more separation between the coil-overs. This may be a simpler solution but may require some other changes depending on what your lower diff. mounting arrangement is.

Pictures of your current setup would definitely help
