I just picked up a set of 2011 WRX wheels for my '96 Legacy Outback, only to find that when I took it in to get the wheels put on, the wheels rubbed the strut body pretty bad. I know that spacers will put extra stress on my wheel bearings, but I'm okay with that if I can run these wheels. So my question is, what size spacers do I need to run in order to run a set of 2011 WRX 17x8s on my Outback with stock suspension?
