These racks fit into a 7/16 groove in aero cross bars so they will likely fit Thule and other aero bars. Confirmed fitment on Porsche Cayenne (955) models from 2003 through 2007, very likely more. This item is new, old stock and appears to have only been removed from the original box, but never mounted or installed. Factory box is aged and splitting at the seams.Thank you and best of luck.
