The PIAA superozzas are two piece wheels(that's why they come with rivets, to keep it together). I too have them on my IBM and love them. I have some rubbing but will get fenders rolled sometime this month. Great choice!
Pictures do not do them justice they are gorgeous in person. I plan on fender rolling as well. Hopefully it won't be too bad until I get it to DMS next week for the 4-point alignment. Then the rolling.
The price is expensive but not extreme. If you want something to fit well without too much rubbing I think you will be hard pressed to do better. 8's and 9's are a great road setup. Pic's tommorow hopefully!
