Wheel spacers will dramatically shorten the life of your wheel bearings, better off getting rims in the correct backspacing.
Spacers act like a lever on the bearings by mounting the wheel out further multiplying the forces they recieve. Getting correct offset rims still mounts the rim on the hub the same location as OEM and they do not lever multiplying the forces even if the offset is different.
Ask your dealer how much it is to replace all 4 wheel bearings... cheaper to buy the correct rims
