Looks like standard C6 sizes on the the tires - is that rear a 285/35/19? 
 
I have z06 brakes and aftermarket Zr1 wheels on my C6 - 18x9.5 and 19x11 rim size and 275/35/18 295/35/19 tire sizes... 
 
Did you need a spacer up front? I thought you needed a 9.5" width rim to run the z06 brakes on a C6 style front wheel.
