-1 to -1.5 degrees up front won't change things much, especially if you keep your toe conservative. you'll get a little better turn it and more grip, but things really don't start feeling different until you get up to the -2.5 to -3.x range, where the car seems like it *wants* to turn, and the steering can get a bit loose/touchy at higher speeds.
My old integra had -2 degrees camber up front, but toe was very conservative. I got a little uneven tire wear, but it was so small it didn't really make a difference. I'm talking about having about 1-2mm of tread left on the outside of the tire by the time the inside of the tire was worn smooth.
And if you ever track your car or auto-x, you'll wear down that outside edge faster than the inside anyway
