Typically, spacers that are smaller than 20mm simply slide onto the hub and do not bolt to the hub. These types of spacers (which are the majority of them) do require longer wheel bolts....even 3mm spacers require longer bolts.
IMO there really aren't much for downsides. I've never seen a spacer cause premature failure of a wheel bearing. The most important part about selecting a spacer is measuring to get the correct size so you don't rub the fender. Everyone I know that sells spacers will not allow you to return them once opened.
