Of couse you'll feel a big difference when you go 3" smaller. Are your stockers and 17's both the same overall diamater (with tires)? That may be a problem too, if the 17's are larger you could be losing quite a bit of HP trying to turn those big wheels. But think about it, if you do go with 16's, that's only 1 inch smaller than 17's, if that's the case, you might as well stick with the 17's because the difference in look is pretty drastic I think, and you'll be gaining quite a bit more looks with very little HP loss compared to the 16's.
