Negative Camber XD

So I recently had an alignment and requested them to put some more negative camber than the stock spec. Normally they align it to .6 and they ended up putting it to .4 They said that was about the best the could do (OME 885, no top spacer, camburg uca's). Anyways. I'm really impressed by what a -.2 difference in camber has made. It seems like Toyota might even have set the factory specs on the high side so the truck understeers instead of going tail out. The front feels way more planted and less prone to under steer, even entering corners with a bit of pace. I don't care for the under steer our trucks normal have and should have done this much earlier. Anyone else run custom alignment specs? Is the X-runner factory specs different?
