you have to work with the seller or store you are buying them from. Not all wheels manufactured will have the identical offsets of that of the XF. You can get close, but sometimes spacers are required. Lug bolts will not always be supplied, so those most of the time will be extra as well. You can custom order your size, but the price goes way up....if I remember correctly our offsets are 22/35.... you can use a chart that most wheel stores will have available as well....plug in your numbers and it will help select wheels. Take for instance, I moved my stock wheels out 5mm, so I had to buy lug bolts 5mm longer than stock.... Wheels can get really confusing...brake rotors/calipers have to play into the mix as well...
