Need 2 wheels and tires
 

Passenger side. Yokohama AS430 tires would be nice too.

Two tires is a bad idea on an AWD car. A worse idea on one with an LSD like ours :)

You run the risk of wiping out the transfer clutch in the tranny & the clutches in the diff.

Better to get the wheels & all new tires, unless the ones you have, have less than 1000mi on them.

Yes, don't replace or change only 2 at a time. A big no no. :o

Can you guys provide any links to literture on this? I've never heard of this before?

That is pretty standard on an AWD. If you check with a tire place, they will tell you the same thing. Unless they aren't a good one. :) If you do a search, there are a few threads about this. :)
