Have not been able to find all of the answers out there. 2010 vs. 2013 GLK any difference in the nuts which hold the wheels on? Appears to be no difference between 2WD or 4WD, but what about between the early & later year models? About to swap out wheels & want to make certain no changes in the cone seat etc. & best way to verify is by the p/n's. TIA.

Question answered as to the lug bolts (not lug nuts). The 2013 Accessory Pkg. wheels went onto the 2010 without problems. Bolt torque is 96 ft. lbs.. Offset of 42mm may make them stick out a little bit in relation to the wheel well but look great. Disappointing that the 2013 version of this wheel is only 8." in width compared to the earlier version which is 8.5". Time to ditch the black 17mm lug nut caps & purchase a set of gray caps from Audi.
