HOWEVER, it looks like last owner did a poor job picking appropriate sized tires.

Not sure who chose your tire sizes but They are interesting to say the least. 
. Your rear is 1.2" larger than your front so you should be fine with Active handling/TC. Your speedo is going to be off though.
Front 235/35/18 - 24.4"
Rear 275/30/19 - 25.6"
Rear is 1.2" larger
Stock C5 diameters:
Front 25.7"
Rear 26.7"
Stock Z06 diameters
Front 25.4"
Rear 26.1"

I would assume that you went with a 9.5 or 10" front, and a 10.5 or 11" rear.
In that case most go with
265/35/18 front - 25.3"
305/30/19 rear - 26.3"
Rear is 1.0" larger than front
275/35/18 front - 25.6"
305/30/19 rear - 26.3"
Rear is 0.7" larger than front

I will measure my wheels to see how wide they are.

I've searched and can't see the stamped size. I haven't removed the wheel thought to check. I did measure the width and it looks like they are 10.5" wheels.

You will need to take the rim off and look at the measurement stamped on the back.
