I have completed 8 20 min track day sessions, 6 autocross days and a total of 8,000 miles on the car. I decided to check the brake pads. I'm in the novice class, HPDE 1, so I'm sure I'm not pressing the car to the max. When I checked the pads the front's had .265 inch of pad left.
Does anyone know what the minimum pad thickness is?
These numbers seem small to me. Too small. Edit: attached is the 2020 service manual on Brake Pads. I think the number are too small, perhaps a typo. A search for typical numbers, not specific to C8 is 1/8 inch.

That's a surprising amount of meat left given the usage -- about half that thickness is wear you'll hit the wear indicator and they are completely done. In my experience the rears wear at about 60% relative to the front. Once you start progressing in pace the pad life gets exponentially shorter. I get about 6-7 sessions best out of a set of front pads (down from ~10). I'm a big fan of the OEM pads; super easy on rotors, zero shudder issues, cheap takeoffs are abundant. Only downside is the abysmal life.

Perhaps posting in the autocross/roadracing section of the forum for advice. On my daily drivers I'd let them get down to 1/8 or 3/16 but I'm not tracking my daily drivers.
Agreed! With over 12,000 track miles on a 2021 C8 Stingray, I get about 2 track days out of a set of OEM pads. On the C8 Stingray, at the end of 2 track days, there are times I have gone down to almost no pad left--not advisable but I also have taken the pads down to metal on metal with having to replace rotors. But then again, I go through rotors on the C8 Stingray like a daily fresh pair of socks! I also have 2 2023 Z06s with CCBs, those pads last much longer on the track. I am in advanced groups on track and race an open cockpit race car in the SCCA for comparison.

Yup min pad thickness is a mater of how much you like your rotors
If you have $1000 rotors then its not worth taking them to the 1/16"
Mark what have you found to be the the best OE type replacement rotor?

I have a 2022 stingray Z 51 did one track day with 520 minute sessions. Probably boiled my fluid because it was the stock DOT three. Brakes felt spongy ever since thought I glazed the fronts. Just put power stop pads on the front and the rear and cross drilled and slotted rotors on the front. Just did a fluid change at the dealership with a DOT for fluid but still feel spongy anything I should check as a pilot and not knowing the brake system is there anything else I should check they are not as tight as they had been prior to going to the track and now I’ve got new brake pads new front rotors and new 4 DOT fluid…… any thoughts would be appreciated of what to do next without just changing random parts out
