ET's are all over the board for all cars. You can't tell me your C8 is going to run an 11.3 at sea level and then run an 11.3 at a 4000 DA track. Not going to happen.
I can tell you at 1000da and 2500da at my home track it has. Several track days and I got it on video.

2000da during the day


900da once it cooled off at night.
You should have been able to run at least a 11.25 going down to a DA of 900. You're leaving ET on the table if you're running the same time in every weather condition.
I'd guarantee you you're not going to pull off an 11.3 on our track up here. Our track is 2250 ft above sea level. The best DA that I ran in up here was 3200.
When I lived in British Columbia and ran at Mission Raceway in Mission. The track there was at 2500 ft above sea level. The da would usually be between 800 and 1500. My old 2014 Mustang GT convertible with heavy 20-in rims on it would run consistent 12.6 at 112 mph. I've Got A Fistful of Time Slips that are only a few hundreds of a second apart.

Oh and by the way. Nice runs you made in the videos!

Yeah man. This is not my first rodeo. I've been drag racing at the track for 45 years. Literally made hundreds of passes.
I understand, I started racing in 1975, but when I made my 1st run down the track at the 2020 NMRA Spring Shootout with a brand new car with street tires, on a green track, I spun my wheels similar to you. By the end of the 4 day event, the track surface was better and after making multiple tire pressure adjustments, I was able to launch and shift without tire spin.

Yes the unfortunate thing is there's always going to be inconsistencies as far as track prep and weather conditions. The track here sucks too because it runs from east to West and we're always running into a headwind. Sometimes the wind is fairly mild but there's other times when it's 10 to 20+ mph. At any rate we're almost always running into a headwind. LOL
Check out this shit! It's only 63° here but look at the da!

Thanks.

Problem is though, there is NOTHING left on the table. The LC is so good, its basically one step behind racing in a Tesla. You just stand on it and let off the brake. No drag radial, no burnout, no skill just on and off switch. GM makes these and the last gen LT cars so consistent, that you can do most of the racer tricks to get them to go faster, and if they see they are making more power they will pull it back. And if there is headroom and they arent getting to the tq demand, they will add some back in. Without a tune or some serious weight reduction, these type of cars are very hard to make faster. Its quite boring. You run the number, and thats really it. I have ran that same 11.3 probably 20 times to the point where I just stop taking it. Its no fun. I sold it and got a 26 and that car was about the same, but since it has the WANG on the back, its actually slower - and consistently slower as well. Wang off and its doing 11.3, 11.3, 11.3...

Heres my 26 doing the dance.

Now lets sprinkle back in the mustang. Horrible wheel hop. If you get traction and thats a big IF, then you are at the mercy of what of the 3428905235435 shift schedules the car wants to use. Then of course there are 27 different spark tables it can blend together to make whatever total advance it wants. And thats if everything goes right. You are fighting ALL the variables with a car like the mustang, and honestly thats fun at times. The C8s are cool for a minute unless you get like a ZR1x or something thats scary fast, but the mustang gives you goals to work toward. And just when you think you are going to meet those goals, it moves the damn goal post lol.

Yeah wheel hop is definitely an issue. My old 2020 GT went from running a 12.7 to a 12.4 just by adding the Steeda IRS cradle braces. That was the first mod I did on my 2026. Pretty much eliminates the wheel hop on the automatic equipped cars.

Yes completely stock 5400ish miles on the odo for the red one. The blue one also showroom stock and had like 900 miles on it at that pass. They are very fast, but again thats about it. There is no skill to get everything they have when using the factory launch control. And nobody has been able to beat it manually. 0-60 is 2.8 easy, like no problem on the street even in the heat.
