Brian, just for you I’m sure the officials will make an exception and allow you to run as much toe as you want.

For the rest of us...there are literally tons of areas where cmc states the part has to be OEM spec but does not state what that spec is. All that said, GM spec for the rear toe of a 4th gen is 0 +/- 0.3 degrees, which translates to something like 0.25”...far more than anyone would want.
