Ideal offset really doesn't change. Keeping the same offset keeps the center of the tire in the same point in relation to the suspension bits. For some reason, the idea has been spread around this forum that ideal offset needs to shift with wider wheels. It's just not true.

But as wheels get wider, space between the wheel and the strut starts to get tight, so reduced offsets become necessary in order to run wider wheels. My experience is with the older cars - I think perhaps the WRX Sedan struts are offset in a manner that creates more strut clearance, so the problem might not be as extreme with them.
