Unless you track the car, you won‘t put any significant stress on wheel bearing loads, or for that mater any other suspension components , if you‘re concerned they’ll wear out faster ( with just 20 mm / 25 mm ones, that is..), it’s a negligible difference . But you should have an alignment done after you install them . And as Jason said, do not cheap out on something like this, saving a couple of hundred dollars can spell big trouble and big ensuing expenses.
