I am thinking about switching over to C5Z06 wheels at all 4 corners for my 2006 C6Z06. The tires I plan to use are 305 on front and 315 in the rear. Does anyone have any experience using a similar setup for track days?

are you asking if the tires will fit the wheels or if the set up will work on your car?

Tires should fit those wheels, do you know the height of them vs. Stock?
Offsets for the rears are close 58mm for a C5Z and 59mm for a C6Z but the fronts will be way off as they are 40mm for the C6Z

Here is the info I have for both cars..

C5Z Front:
Wheel size: 17 x 9.5
Offset: +54mm
Tire Size: 265/40/17
Back Spacing: 7.38” (187.35mm)


C5Z Rear:
Wheel size: 18 x 10.5
Offset: +58mm
Tire Size: 295/35/18
Back Spacing: 8.03” (204.05mm)


2006+ Z06
Front:
Wheel size: 18 x 9.5
Offset: +40mm
Tire Size: 275/35/18
Back Spacing: 6.82” (173.35mm)


Rear:
Wheel size: 19 x 12
Offset: +59mm
Tire Size: 325/30/19
Back Spacing: 8.82” (224.09mm)

Thanks for the info.

I was more worried about the tire fitting the wheel and working well since I had heard that a 295 was the regular size for a 10.5 inch wheel.

I have run 315 Hoosiers on the 10.5's for a couple years, no issues.

Perfect sounds like I have my setup then!
