Actually, i just went trough this. Make sure you get "direct fit" not "multifit". the multifit, uses the studs to centre the tire "stud-centric"and the direct fit uses the hub "hub-Centric". I just had a pair of multifit removed from my vehicle, the shaking was unbearable!.. went to kia, picked up a set of OEM rims @$64 a piece and now were smooth as glass.
As it was explained to me, "if you use the multifit, there is always a chance that the rim will not be installed 100% centred on the car....trust me this is not what you want . . . bouncy bouncy"
