I don't think 305s would stick out. That's a stock size for the rears already.
Some folks even run a square 315 set ups for the track. I would hope they fit just fine.

People do all sorts of stuff without recalibration but GM has to do it and make sure it will last. The Z/28 was also designed to run 19" wheels. I'm sure that was taken into account when they set up the suspension.
