Options for 18s all around on C6?

[FloydSummerOf68]

What are some options that people go with to do 18s all around on the C6? The reason I ask is I'd like to have more selection on stickier tires for DD. Thanks for any help

Hi Floyd,

I did OEM Z06 fronts, 18x9.5 all around. Lots of tire choices.

I used 275x35x18 on the front (stock Z06)

275x40x18 on the rear

I have pictures and will E-mail to you so you can see fitment. Send me your E-mail and I will return with pictures. I don't know how to post on the Forum.

Several are using the OEM C5Z rear 18x10.5 at all four corners.

This is actually a good idea. Then I could go back to a GY GSD3 setup on my car.
Would there be any need to recalibrate the speedo if I change the rear to an 18"?

Not if you get a sidewall that is a little bigger than what comes with the OEMS's. I ran 18's all around for a while and had no problems. IIRC I ran a 285/40-18 and was within 1% of the original size. Only reason I went away from it was because I didn't like the wheels I was running. Would do it again if I could find the right wheels (and could afford them). Good luck.
And no, I didn't need to recalibrate the speedo, it was within 1-2 MPH, again IIRC.
