Hey - I am a regular on Brooks' channel and I can tell you he has probably one of the worst drag strips which is proven by lower than usual trap speeds across all the brands and models. He probably has the slowest recorded Turbo S times and his Z06 runs have been really slow (although times are good). I have no reason to doubt that this place had mediocre DA. Everyone comments there how the trap speeds are unusually low. The Turbo S was trapping 128-130 which is really low. He has had two different Z06s in his channel with many runs with him and other driver at the wheel and he never gets over 128.5 mph across several months this year. His 600LT runs were also very low (and that car even had a tune on it).
Point being, he races is in sub optimal conditions.
GT3RS has much more aero than a non Z07 Z06. It makes 992 lbs of downforce at 186 mph whereas Z06 is 364 lbs at the same speed. They have very similar front tire widths (265 vs 275 and both 20"). And OP has been racing his Z06 with drag radials and the GT3RS in the video (and many other videos) usually come with Cup2 tires (non R). I dont think gearing is the issue here and I thought DCT in the Z06 was as fast as the PDK. Even if its somehow not as good as some are saying here, I doubt it would explain the trap speed difference.
What also puzzles me is GT3RS 60-130 time is 8.3 seconds. I believe Z06 does the same 7.3 seconds. How can a car be so much faster 60-130 but somehow in 1/4 mile this isn't apparent? 7.3 seconds is almost as fast as Turbo S in stock form.

Wait does a c8z do 60-130 in 7.3? That’s faster than than the c7z right? Could’ve sworn it was 7.8 or 7.9 for the c7z.

I really enjoyed the video Jessie!! Thanks for sharing it!! Cool how you are still so enthusiastic about the car and it seems to be working pretty flawlessly for you. At times the miles on it haven't necessarily been easy ones.

I bet in the real world and not on a prepped track, their 60-130 is near identical. I've seen a lot of cars run some solid times at the track for their 60-130 but, they can't quite do the same on the street.

but wouldn’t a street 60-130 always favor the c8z because of the immediate traction?

Expected. The poor trans tuning on the C8 bases hold them back tremendously on the low end as seen here. The quick heavy shifts that kill boost isn't something power can really remedy. Once it gets to its longer gears it can actually hold the boost and fly away. Conversely the Z06 gears become too long at high speed and it slowly needs to find the power at the top of its RPM band.
They're pretty similar. C7Z dragy times are all over because of transmission, aero, weather conditions, etc. The C8Z has less aero configurations and has more consistency because it's NA and has a better transmission. An auto C7Z is ever so slightly faster than a C8Z. It has less weight, more torque, and less drag.
By time cars are going 60 they will both have traction. If you start at 50 or so then C7Z will have sufficient boost built. It's torque if anything will give it an advantage in a rolling start.

That’s true. It’s just that some people have different ways of clocking a 60-130. By starting at 50 or right below 60 and some people start from a low mph (although i bet a car with better traction), to get optimal 60-130 times.

Plus it is a Z06! 140 mph plus is easy! Look to JB's blown C5's C7z06 for an example!
