Then it became an easy thing to change at the track only requiring a few minutes to jack the wheel on each side and move the plate.
With the tie rods in front of the centerline, when you add negative camber, the toe goes outward. Hence we set -1.5 degrees camber for street use with toe dead center on the factory spec, and then when we moved it to -2.8 the toe moved outward to just a touch over 0.
As an aside on camber wear -- on my E39 M5 with GC plates, I ran -2.4 degrees front camber for over 10 years without a significant wear issue as I kept the front toe-in small (0.02 degrees).

^^^This. A "lot" of negative camber on the street is fun in my opinion.
