Found some 18x10.5 and 18x8.5 c6 replicas. Need tire suggestions for rear. Size? Drag radial vs slick? Brand? Street driven occasional auto x at qualcomm. Any input is appreciated thanks.

In theory, you'd want a 285/30 on an 18x10.5, but 275/35s can be had super cheap, and 295/35s would be the popular look for street use. For autocross, sell the 8.5s and get 2 more 10.5s, they can tuck if you get the spacer thickness right.

^^^ Yeah as he said.

I run 285/35/18 on the front and 285/40/18 rear. 285/30 is shorter than stock. 35's worked fine on the rear, 40's required rolled lips and a slight bump on the inner fender. 18x10.5 all the way around.

Thanks for the suggestions. Going 285s..looking for c6 style 18x10.5 like the ones i have and it seems they dont make them. Only 19s.. most likely getting a mismatched set i can swap for auto x..

Any input on slicks vs drag radial?

If you plan to autocross and any real street driving, forget slicks and drag radials. they wont hold up
