The stock SS set up yields 27.7 front and 27.6 rear. Hmmm. More research. Specs are from https://tiresize.com/calculator/

Yes, but remember GM has each model and sub-model programmed for the tire sizes they come with.

The SS 1LE and the ZL1 1LE will have their own calibrations.

As a general rule, you want to keep the same delta as stock no matter the changes you make.
