I autocross my 03 wagon and used to get the front inside tire wheelspin when exiting a tight turn in 1st gear. Not only would it spin, but it would actually hop up and down. I had no idea that the wheel was hopping but course workers commented on it a couple times. I learned to not just stomp on the gas pedal during exit of a turn. It is an analogue input, after all. This really helped my times. In autocross, wheelspin in a corner can put you off line and it wastes power as heat in the spinning tire, not to mention it overheats the tire and probably the center diff.

But what eliminated the wheel hop (and bettered my times) the most was better dampers (went from KYB AGX to Koni inserts), an upgraded front sway (Whiteline 22mm adjustable), and 245 width Starspec Z1's on 17X8's. The tires probably didn't help the wheel hop issue as much as the dampers and front sway, but they all helped my times by an enormous amount. I beat everyone now. LOL

if you have enough traction (through tires, mods, and driving skill) that your wheels never spin, your open diff[s] become way less of an issue.

And yes, some wheelspin while launching in a straight line is fine. Note I'm talking about turning and accelerating.
