"Thanks for asking. The 6 inch backspacing on the Black rock Wheels 910 Intruder in 18x8.5 and a 5x120 bolt pattern are really close to your factory 6.25 inch backspacing so they will fit."
Amazon has their compatibility check (like other sites). If Amazon is wrong, you could always send back and get all your money back, but what a pain.
Isn't oem 6.5" backspacing?
Also, what are you going to do about the hub bore on those wheels? How about the poke out? Have you tested your turning clearance?
