Pro gears vs street gears

Are they already set up in a rear end? If not I wouldn't order one for a typical 10 second street/strip deal.

its a new S60.. but i think he said he had a set of pro 4.30 gears laying around.
I street drive it, but don't go on long jaunts, too worried about having a flat, etc, etc.
