Yea, my thoughts exactly, I think 9" is what we need

Assuming you have coilover suspension with the perch above the tire, an aggressive track-oriented alignment (over 3 degrees camber), and rolled fenders, you can fit a 17x9 with an effective offset of 30-33mm with a race-oriented 255-40-17 street tire such as the Bridgestone RE71R. This is the most that is really possible while maintaining full range of motion.
As you start subtracting from that list of preparation, what you can accomplish will go down. While I have not personally tried it, a normal 235-40-17 street tire on a 17x8.5 should be doable with a more moderate amount of camber (2+ degrees) and unrolled fenders as long as the offset is just right (ie as close as possible to the strut).
