I found that H&R springs makes a hub centric 5mm spacer that comes with longer studs. It's a really nice package and made from milled aluminum instead of cast. The cost is about $80 and it will save you from having to go to new wheels. Have you noticed any squealing from your brakes. After a few hard stops, I've developed a little squeal that happens when you stop on a turn, ie. into a parking space. It occasionally happens on the road, but not often. My car stops really well right now and I'm still adjusting to not using as much pedal effort.
