What car are you putting the wheels on? I found my selection of rims was heavily restricted for my celica, as it's got an uncommon stud pattern. Conversely, 4x100 or 5x114.3 bolt patterns are common as hell, so you'll be on easy-street if it's one of these. Cruise the websites of big tyre franchises (here and O/S) to run through their selections, by size + offset etc. etc.
-Perhaps fellow Toymods users would have suggestions/directions for you, if they knew what you were putting the wheels on.
