+1.
Suspension and tires are usually the weakest link on the stock Impreza (particularly so for the '08 if we are to believe the reviews thus far), but nothing really exists yet in the suspension department, so. . . tires.
After autocrossing today on Falken Ziex ZE-512s, they are my favorite all-season tire EVAR. They have pretty remarkable grip for an HPAS tire.
