For street driving I have no desire to run any more than -2deg. I agree that my front camber is a bit too mild now, though. When I go to the track, I'll likely shift over to around -2.75 and work from there. I have a pyrometer and I know how, and intend, to use it.
Once I go to my track setting on the front, the rears will have camber that is slightly lower as I know is ideal. Because I don't have camber arms to easily adjust the rear, we went to a value that would work on the street and track.
