I googled this question and even though MSRC is std the search results said PTM is not. I also went to the Chevy Build and Price tool (even though prices are not provided). When selecting base GS you CAN’T select PTM. Once you add Z52 Sport, PTM is auto selected. This seems odd in that PTM is not listed as part of the Z52 packages (either of the 2), Also in the Z51 package if you get MSRC you get PTM. Seems strange but looks like if you want PTM you must get one of the two Z52 packages?

I noticed this earlier today and have inquired with my dealer who is looking into it. I'll report back what I learn. I think that "option" for PTM has to be some bullshit so more people get Z52, because if you go to trim and select "compare all features" you'll see the following...It also shows as standard in the GM Order Guide

I emailed Mike Brink of “Brink of Speed” and asked him if he thought his 2LT base GS would have PTM. If anyone would know, he should. He placed an order early. And I’m guessing he expects his GS to have PTM, but not sure. He specifically stated on his Utube outlining his spec that he didn’t choose either the Z52 Sport or Z52 Track package. Since he is one of the early orders of a base GS, and he will be posting content about his new car for his channel, we should get the answer to this mystery. If I get an email reply from him I’ll post it here.
Did Brink ever responded to your question? I was wondering as well and I'm getting 2 diffrent answers at MacMulkin, said that PTM is only part of the Sport or Track packages on the GM order guide is wrong. I emailed DrivewithAllen and he said that TPM is a fundction of Magride so it should be included. Getting mixed answers, nobodys seemes to know for sure. The online GM configurator confirms that you need a package to get PTM. My workbench order does not show PTM as an option since I'm ordering the base GS. So I'm thinking PTM will not be included.
They also show 6-piston front Brembo brakes as an option, but they come standard on the base Grand Sport just with different rotors and pads no? Or did they do like Dodge did with the new 6.4L Durango R/T and make Brembo’s an option, meaning the fronts are 4-piston calipers from Z51?
No response yet from Mike Brink. At this point I don’t think anyone will know except the Engineering staff on the Corvette team. I think it would take new software to NOT have PTM if you have Mag Ride and ELSD. I have a hard time believing PTM is not on the base GS. Can’t wait for someone to get one (base GS) and get on Utube and show us the information screens as you toggle thru the various modes. The Z51 model is specific that PTM is included with Mag Ride.
I just was on Justin’s Horsepower Obsessed live Utube broadcast he does on Monday nights. I posted this question on the live chat. He discussed it right off the bat. He thinks PTM s integrated with MRSC but he is not sure about the latest version of MSRC. So he thinks it is but is not sure. He said he will attempt to get a solid answer from his sources.
It literally says in the order guide and the build & buy trim explanation I posted above that it's standard for all grand sport models. If they renege on that it's gonna be some real bullshit.
Are you getting a Z52 package? If not did you want PTM for sure?
No I'm getting touring. Yes I want and expected PTM. I don't have immediate plans to track it, but if I ever do I was planning to upgrade tires, rotors, pads. Order is already at 3000 so nothing I can really do about it now.

I emailed a guy named Shane Webb at the Museum. He said PTM is on all Grand Sports. He said the order guide is correct. This means the AI search results are wrong.

Makes me wonder why the build & buy tool is also wrong. thanks for the update and to Shane for confirming!

On the Stingray PTM requires both Z51 (eLSD) and MSRC. Z51 without MSRC doesn't have it nor does MSRC without Z51. While the base GS comes with MSRC is it stated anywhere that it has eLSD? I'm assuming so (that would be a big omission). I suspect the base GS will have PTM but it is possible that GM could de-feature the base GS if they desired.
Edit: Now that I see that GM doesn't endorse the base GS for track use I could see GM not wanting to spend the money to develop the PTM parameters for the softer springs and AS tires on the GS. It may only have Competitive Driving mode like the base Stingray.
And here is some more evidence from the news release that not all Grand Sports have PTM:
"Plus, standard Magnetic Ride Control, available Performance Traction Management, and so much more."
Below was copy and pasted from the chevy site. Look at the below words and diagrams. It doesn't say "when equipped" or "optional equipment" the GS has ptm standard according to the website under the grand sport tab.
The standard Driver Mode Selector allows you to choose from Tour, Sport, Track and Weather modes as well as the customizable MyMode. You can also activate the customizable Z Mode by pressing a button on the steering wheel. The modes affect throttle response, suspension and overall handling for a truly tailored drive. Tour Mode
Provides a balanced blend of comfort and performance, ideal for regular city and highway journeys. Sport Mode
Enhances responsiveness for sporty environments, with firmer suspension and more aggressive transmission shifts and steering feel. Track Mode
Prioritizes performance on closed courses or tracks, allowing for maximum control and speed. Weather Mode
Optimizes the car's performance for slippery conditions like rain or snow by adjusting throttle response and traction control. MyMode
A personalized driving profile for everyday use, allowing you to adjust settings like exhaust sound level, steering feel and suspension to your preferences. Z Mode
A quick-access, driver configurable performance mode allowing drivers to personalize settings like Performance Traction Management, steering feel, engine response, exhaust sound and brake feel to match their preference.
All GrandSport will have both. ELSD and Mag Ride. Which in turn equals having PTM.
And...right from the chevrolet home page for Grand sport.
Having eLSD and MSRC doesn't mean GM has to include PTM, it means they can. And the information from the GS home page is generic, it is describing what you get when you get PTM. But here is what you get when you go to the GS configurator, add summer tires, and then go back to AS tires:
Changes Required
Changing the Michelin® Pilot® Sport All Season 4 275/30ZR20 front and 345/25ZR21 rear, performance, run-flat tires will also change the following:
REMOVED
Z52 Sport Performance Package
Performance Brembo® antilock brakes
Michelin® Pilot® Sport 4S 275/30ZR20 front and 345/25ZR21 rear, high performance, run-flat summer-only tires
I called Shane Webb just now at the Museum. I had sent him a follow-up email questioning the Configurator making you choose a Z52 package to select PTM. Shane contacted some GM staff and said the order guide is , in fact, wrong. It is being updated. You must select either Z52 Sport or Track to get PTM on GS.

Nice of them to figure that out AFTER I placed my order. ******* *****. What other mistakes (lies) and omissions are there??

PTM not std on base GS?
