These Enkei RPF1 wheels are lighter and less expensive than most any other wheel in this size . Takes a 73/67 ring for those that want the hubcentric rings, available elsewhere on the website. Narrow extended length lugs are recommended (see McGard Spline Drive lugs or our forged lugs here on our website). See pictures of these on our MazdaSport Magazine project car...on THIS WEBSITE in our forum wheel gallery. Note that center caps not included but available separately (see them in caps section under Accessories).
