I am looking to compile some quick "go to" info for the C7 Non-Z51 owner that doesn't want to use their stock wheel setup. That being said I would appreciate those who can answer the following questions.

1) has anyone CONFIRMED that the Z51 19"/20" OEM wheels will work on a non Z51 C7 without any issues?? YES - Confirmed by slief. Thanks!

2) Does anyone have the 'complete' wheel specs for both models?

NON-Z51 fronts -
Weight: 52 lbs.
Width: 8.5"
Height: 18.0"
Offset: +56
Bolt pattern size: 5 x 120mm or 5x4 3/4"
OEM tire size: 245/40R18
Max tire size that will fit OEM rim: 275 mm (unconfirmed) (closest size match at this width: 275/35R18)

NON-Z51 rears -
Weight: 61 lbs.
Width: 10.0"
Height: 19.0"
Offset: +79
Bolt pattern size: 5 x 120mm or 5x4 3/4"
OEM tire size: 285/35R19
Max tire size that will fit OEM rim: 305 mm (unconfirmed) (closest size match at this width: 305/30R19)

Z51 fronts -
Weight: 51.5 lbs.
Width: 8.5"
Height: 19.0"
Offset: +56
Bolt pattern size: 5 x 120mm or 5x4 3/4"
OEM tire size: 245/35R19
Max tire size that will fit OEM rim: 275 mm (unconfirmed) (closest size match at this width: 275/30R19)

Z51 rears -
Weight: 60 lbs.
Width: 10.0"
Height: 20.0"
Offset: +79
Bolt pattern size: 5 x 120mm or 5x4 3/4"
OEM tire size: 285/30R20
Max tire size that will fit OEM rim: 305mm (unconfirmed) (closest size match at this width: 305/30R20)

- NOTE - I do not know if these max tire sizes would rub or not, these are being provided as the max recommended width tire for the given rim width. Wider may be possible, but I wouldn't recommend it!

3) what wheel options are available for a non Z51 C7 owner that is looking to jump from factory 18"/19" to a 19"/20" setup?

Looking to keep this thread updated so us non-Z51 folks have a quick reference page for the info. Thanks in advance!

The answer to you first question is yes. The OEM Z51 19/20" wheels and tires will work on the non Z51.

I don't have the specs other than the non Z51 uses 18" fronts and 19" rears where as the Z51 uses 19" fronts and 20" rears.

That said, a quick search of Wheel Size in the C7 section will yield several threads on the subject in which I'm sure you could find your answers.

Thanks for confirming the first questions! I have searched and you are right there is info out there, but in some cases I found conflicting info. Just wanted to try to get some hard confirmed specs. Im updating the first post with what I have found so far. If anything is off feel free to chime in and keep the info coming.
