Default C8 wheel spacer question

I see the 15-20mm spacers mentioned a lot. Has anyone used anything wider than the 20mm ?
I need to push out the rear Weld wheels on my Z. And no I’m not buying new wheels 😉

There are 30mm spacers made by H&R. I have used both the 20mm and 30mm hub-centric on my C8 Z06 with zero issues. Good luck!

I have one C8 Z06 with the H&R 20mm rear spacers and stock wheels, the wheel/tire sit right at the edge of fender with no rubbing. The other C8 Z06 (track day car) has H&R 30mm rear spacers with MRR 20x12 wheels with a 50mm offset, the wheel tire tend to sit more inward at top as a result of my -2.2* camber track alignment. I'll try to get some pics posted.

Even better news is you track your car and not just for looking good. My track day is 1/4 mile and roll racing so it’s great to hear this

The spacers do make the car look better, overcoming a C8 Z06 design shortcoming IMHO.
Yeah I hope to track the hell out of the Z06 this year, the car is all ready, wheels, tires, seats, harnesses and bar, rotors and pads.
I just tried to send pics but I guess they didn't go so I'll try again.

Where did you buy the H&R spacers?

Is there a way to tell if there are spacers without taking the wheels off? On my 21, which I bought used, the lug nuts are much deeper on the rear wheels than the front.

That's normal for the rear lugs to sit much deeper in the wheel. You would see the spacer sandwiched between the wheel and brake rotor (usually black or silver in color).
