You can check by the donor vehicle make, model and year.... http://http://tinyurl.com/3j2tv Or if you want, do a google search on this particular site (must have the Google Toolbar installed) Have the page open, do a 'current site' search for youe bolt pattern: For example, follow this URL for 4 x 114.3 mm: http://http://tinyurl.com/54lljv Then, what I do is (in Windows) click [Edit], then click [find onthis page], type in 4x114.3 and click [next], [ next], [next], etc....to have it find the particular size I'm after....works like a charm!! I hope this helps someone in their quest for some cool wheels for their mini!!!
