You need 5x114 (05-07) front struts which will bolt up just fine to your car. For the rear, you CAN use your stock struts but it will be very mismatched and not handle well. I would recommend getting matching front and rear struts from an sti (05-07) and notch the rear strut towers to fit the top mounts. There is a write up on how to do this if you search.
