I had the same problem before installing the adj LCA's. The outer edge would wear substantially faster than the center and inner areas. I installed the adj LCA's with -2.25 camber to get even tire wear.
Realize that this isn't a one-time fix - you'll continue to need to add more and more negative camber as you become a better and faster driver. Today, I run -3.6 negative camber in order to achieve even tire temps and tire wear.
Before LCA's:
Today with -3.6;
