Default C7 Z51 max rear tires for stock rims?

Can someone share the max rear tire size (width) is for a Z51? The stock tires are nice, but I like em a little fatter.

I didn’t want to push it so the widest I did was 305.

My Z51 car w/ 305s on stock diameter (10") rim. These are base 19" rims for my AutoX setup, but will show the fit. Good fit & not too pinched. I wouldn't go any wider, though. My .02...

Do you have a shot of the width from underneath / behind the car?

Just purchased a 2016 Z-51 which I plan to autocross. Not a newbie to AX with C-5's but new to C-7.
In your photo you indicate "base 19's for autocross". Are you using 19's on all wheels to change gearing? I will be using Bridgestone RE-71's, any recommendations on tire size and wheels?

Using the full 18/19" base car setup w/ 265/305 RE-71 tire combo. Cheaper/lighter/wider w/ them rather than a 19/20 setup. Enjoy your new car!

I'll hopefully remember to take additional pics when the AutoX setup is back on the car.

How many inches can you drop the stock bolts? Looks like 1 1/2" plus.
