A lot of useful information in the video for those of us who track our cars.

Tires/brakes (stock), alignment specs (F/R), tire pressures (hot), all electronic nannies off, driver POV camera angle that includes steering input. Car driven at the limit of adhesion with different lines tells you a whole lot about the handling of the car than just the regular line lap after lap after lap.

Good summary at the end in regards to how the C8 Z51 handled the track sessions, tire wear, brakes, oil/tranny temps,. etc. (could tell that the car's tire pressures were set properly when hot given that the right rear tire had a higher (lukewarm) tire pressure than the other 3 tires given that Willow Spring is a clockwise track that has a lot of right turns that loads the left rear tire more needing more air to be bled out.

And to expand, not all cars use the same lines through every turn, a FR platform might not use the same optimal line as a RR or a MR car. On a mid engine car you can get on the gas a lot earlier than on a FR car. Also this was his first time driving the C8 at the track. I have been on track at Willow Springs, and unless you have driven the track you probably can't make out the camber and elevation changes just by watching a video.

The only critique that I would make would be to make sure to fill the tires with air to the recommended tire pressures before driving back home to prevent the shoulders from wearing down.

It is well known by now the media fleet Porsche's used by C&D where stripped out cars without FMVV, without A/C, without electric motors (to include wiper motors), without infotainment, and with fuel race tanks to boot! Couple this with a switch to race tires and associated on the spot tuning before track tests and you have the ultimate car magazine queen which fails repeatedly in real settings to repeat their "magic".

I am far from drawing any definitive conclusions and a victor from the video. IMHO it simply shows the cars in stock form are much closer in reality than narrated by the number crunchers at C&D.

I humbly suggest to C&D that instead of pumping the brakes on the video they actually come up with one of their own showing in detail what they are testing instead of telling me the video is lying to my experience and I should instead believe their numbers pulled out from the twilight zone.
Wait you’re having a hard time believing that a properly driven GT3rs is faster than a properly driven C8 on that track?

Sarcasm, I hope.

That GT3 RS was far from well driven (OP post), at least 5-8 seconds off with those sad lines what the car could do if driven well on the proper lines. I would not sign him off to run solo being that far off the apexes. I expect somewhat consistent lines and within 12-18" of the apex to sign off students. The first video of that GT3 RS would not meet that test on virtually any one lap, much less consistently.

I have first hand experience with C&D editors racing in SCCA and it wasn't a favorable impression.

It certainly sounds that way. I can’t believe anyone would be comparing these two cars in the first place..with all things being equal the Porsche will win every time.
The base C8 is a great car. However I think we will have to wait for the Z06 for that particular car to be unseated, realistically.
FWIW, the Stingray should stand up quite well against, or surpass a 911 Carrera S in performance and finish, which in and of itself is quite an accomplishment.

Hard time? ask C&D; they are the ones having a hard time?
GT3RS has 511 SAE HP and 335 SAE lb ft torque with a weight 3300+ pounds and race tires.
C8 Z51 has 495 SAE HP and 470 SAE lb ft torque with a weight 3600+ pounds and sporty tires.

Consider the total picture and let's ask C&D why THEY are having a hard time believing a C8 can keep up with a GT3RS?

Good and also good we can all extrapolate something different from the video so thank you again for posting it.

If you keep repeating the above enough, it might become true.

Great video. Thanks for sharing. The kid can drive. The C8 sounded great, and the shifts were impressive.

You are late and complaining to the messenger.
Members of the German PFF Porsche forum have had the 911 GT marketing Ring record boondoggle figured out more than two years ago. They are the reason Porsche rectified the tires portion of the record as well as clarifying the stripping done to the cars. Probably also the reason Porsche let the head marketing guy find employment somewhere else.

Enjoy the read and by all means complain to them as well if you like.

Interesting that so many here comment that the 'kid can drive'.

As an instructor I found consistent mistakes in his driving and would put his skill level at a novice - lower intermediate.

As other instructors have mentioned, the GT was all over the place; not sure what organization allowed these guys to drive solo.

Cool to see s few Type-R's (I have one in addition to my Z06) hanging with these guys in the corners. But they are at an HP disadvantage on Willow's big track.

Looked like the C8 handled the notoriously bumpy T8 better than the GT for some reason.

I enjoyed watching it though. Good to see people having clean fun on track.

Boy I hope VIR re-opens soon!

Interesting to see the rear come around @ 1:14, & @ 1:55 nice recoveries!

I probably would have put a bit more heat in the tires before pushing like that.

@ 4:06 the tires are coming up to temp & the car gets into a nice slide.

Overdrove the section at 4:39, but agreed - very nice driving!

From what I can gather, these C8's seem to be really searching for front-end grip. I hit a plateau in my C7 Z51 where I could not seem to find more mid-corner\exit speed due to lack of front-end grip.

My C7 Z06 with the wider tires has much more front-end grip.

So the mantra for amateurs, even experienced ones, is generally ‘smooth equals fast’. Not sure I’d call those smooth laps at all! lol

Jumping in the car for the first time and trying to find the limits quickly in a car that isn’t his, I thought the throttle and steering inputs even with the slides were relatively smooth. It did say they were trying different alignment settings and not sure if this is the one they determined to be the best or not, maybe Adam or Louis will chime in as they’re members. Here’s same driver/same track in another borrowed car with the owner in passenger seat, appears to be a couple seconds faster than C8 lap time on wider stickier rubber though of course.

Man that GT is nice.

That catch at 1:42 was great.

<whew>

What track were these at? Lots of runoff. My spins at VIR sometimes result in an expensive encounter with Mr. Tirewall.

Ouch, that’s what I like about the tracks in Texas. Fortunately I’ve never put more than 2 off, this was Motorsports Ranch Cresson which is a local one to DFW.

DE instructors are focused so much on a single line (the classic line) 100% of the time and assume that anyone who takes a different line doesn't know how to drive a car on track.

The video author is definitely not an beginner or intermediate driver, someone who has car control skills that can place a car anywhere on track safely without been a moving chicane for the other cars behind is not a beginner, he is not dive bombing anyone in the turns, nor applying any undue pressure.

There are lots of younger folks who have karting experience that can drive circles around people who do DE's (instructors included). People who have done wheel 2 wheel know that you need to be able to take corners with different lines sometimes to present yourself in the side mirrors for the cars that are in front of you or to have a better exit speed or different exit line to do a pass further down... BTW: The Type-R as well as the white BMW in particular were moving chicanes, completely oblivious about the cars behind (GT3RS/C8) been faster.

Here is the same video author driving his GT500 at Willow Springs not pushing the car as much but still demonstrating car control skills.
