Stock Alignment

Does anyone know what's the factory caster angle? I've found some info about stock recommended camber of -1.3 front and -1.5 rear, but nothing about caster.

IIRC, it is 7~7.5 degrees.

It is also important not to confuse degree and minute vs degree and decimal:
Front camber spec is 1deg29min nominal which equals 1.48 degree, while rear camber is 1deg50min nominal which equates to 1.83 degree.

Note that caster is not adjustable on the F8X platform.

The C7 and C8 Corvettes have adjustable rear caster...

Yes, you are absolutely right. From a pure suspension geometry perspective, there is just as much a caster angle on the rear axle as there is on the front axle. I wrote my post in too much haste and now edited it . Caster mostly has a self centering effect on the steered wheels, hence my hasty reply.
