I don't think that any tire that touches the track is actually zero grip; it's more of a minimizing the grip situation.
If you're talking about Slot.It zero grips; either the 17x10 or the 19x10, then there does seem to be a surface difference between the tire as it comes from the package and the same tire after it's been trued (sanded). I'm not sure if there is a measurable difference, but there definitely is a difference in the feel of the tire tread before and after sanding.
I overcoat my zero grips, once they're trued, so that the grip is as minimal as I can make it.
