BTW, I wish I didn't have the Performance Breaks or I'd go with your set-up with 17x8.5!
Are you talking about factory PP? They have a ton of room with the RSe16's. I love these wheels for the price, weight, size. I bought another set and they're still in the box waiting for me to decide which track tire I want to use next. I'm waiting to see how the new RE71RS's will do on track. The Aussies seem to really like them. I can't wait until they're released in the US. If they don't get released before next season starts, I'll do RE71R's for autocross and RS4 for track. I don't have enough camber or a wife that will be ok with A052's, even though they're stupid fast for autocross, but our primary site is an old cheese grater of an asphalt runway. We've had guys swap back and forth with R comps and 200tw and see very little difference in times and grip. It's a terrible surface. I might even be fine with RS4's out there.
