Thank you.
It will stick out 26mm (1") further than the OEM C5 coupe or vert wheel and 10mm (0.4") further than an OEM C5Z06 wheel.
If you have a C5 with OEM coupe or Vert wheels you will see that the wheels are somewhat sunk in the front fenders. C5Z06 OEM wheels are nearly flush with the front fenders.
If you want to do calculations on offsets yourself here is a wheel offset calculator link:

And here is the C5 and C5 OEM wheel specs:
Backspace/offset dimensions are as follows:
C5 (coupe/vert):
Front 17x8.5", 58mm offset = 7.03" backspace
Rear 18x9.5" 65mm offset = 7.81" backspace
C5 Z06:
Front 17x9.5", 54mm offset = 7.38" backspace
Rear 18x10.5", 58mm offset = 8.03" backspace
C6 (coupe/vert):
Front 18x8.5", 56mm offset = 6.95" backspace
Rear 19x10", 79mm offset = 8.61" backspace
C6 Z06 and C6 GrandSport:
Front 18x9.5", 40mm offset = 7.22" backspace
Rear 19x12", 59mm offset = 8.82" backspace
C6 ZR1
Front 19x10 40mm offset = 7.22" backspace
Rear 20x12 59mm offset - 8.82" backspace
C5 and C6 wheel circle:
5 on 4.75" (120.65MM)
Center hub dia. 70.3mm
Don't forget to add a little for the tire bulge beyond the edge of the wheel.............
