For your camaro based on your name description: 2020 1LT

The offset will be important depending on the type of brakes you use.
6 piston Brembos is a larger brake system, than like my car which uses 4 Piston. Offsets will be different between the two.
Rubbing won't really be the issue on those wheels if I am not mistaken, the offset with brake system will be.
An offset, if I'm not mistaken is how far from the center of the wheel itself to the inside or outside of the wheel. How far from the center line the wheel hub/spokes are from that center line. Someone please correct me if I'm wrong here.
