I assume even the base GS will have PTM because it has mag ride. Wouldn’t that PTM have a “track” setting even though GM advertises the base GS as a Touring Suspension? Wonder how the MSRC shocks will feel in the “track” setting of a Touring Suspension? What I ‘m getting at here is you should certainly be able to enjoy good track performance from the base GS compared to say the SR Z51, even considering the all season tires on the GS? Anyone care to guess?

The tires, brakes and suspension help make the Z51 more track worthy, but the cooling upgrade is necessary.
No PTM on base Grand Sport according to the official press release
At this point, I'm not even sure GM knows for sure what's going on with the 2027s with all the contradictory info that seems to be out there on some of the options/packages. Seems like a lot of things that are listed one way in one place then listed differently in another.
It seems very odd that the Z51 with MSRC has PTM but the base GS with MSRC would not have PTM. Especially since it looks like the base GS has the thicker heat exchangers. This is confusing.

I would probably defer to the Order guide, and assume the base GS also gets PTM. Media press releases are notoriously disconnected from production/engineering.
Yeah, I know its early but those packages need to be explained a little better. Like "touring." What does that mean? Is that like base Stingray's touring? Is that like .80g's? Cause that would suck. My grandmother's Brougham has a "touring" package. That doesn't mean its good. Is GS touring better then a 951? Are those two piece rotors? What's the spring rates? Why can't I order summer tires separately? What is a performance tuned "stiffer" suspension exactly? How is that achieved? What's the bar sizes? Why can't I get low dust pads on the Z52 Sport? Are the collars adjustable? Which ones?

I too would love spring rates, or at the very least percentage stiffer for the Base>Sport>Track, also if they come with the stiffer Z06 lower control arm bushings. Anti roll bar sizes, and if there's an MRSC tuning difference between the models. Sadly we won't get this info until they start updating the parts catalogue or when people start tearing their GS's apart.

I see this quoted a lot, but peak performance in optimal conditions are very different than on track. I bet after a lap or two, at most, those tires are going to reach their thermal capacity and fall off a cliff. All seasons might be fine for a hoon or two around a couple of corners but should never be considered a serious alternative to a dedicated summer tire.

For sure, tires just like brakes have their optimum temp window and it’s why they’re packaging the brakes/tires the way they are.
The Z52 Sport and Z52 Track suspensions are the same, only difference is the Calibration for the difference in the tires ( 4S v Cup 2R).
Do you have a source for this?
The Z07 has much stiffer springs and roll bars which equates to about an 8% higher ride frequency. This was done to handle both aero loads and increased lateral loads of the cup 2 tires over the standard Z06.
Per the graphic above it seems like Z52 track is indeed stiffer than Z52 sport, but curious if it's basically just Z07? I mean the cars will be the same weight and on the same tire.

From what I see Z52 Sport and Z52 Track both say “performance tuned stiffer suspension”, which seems to imply they have the same stiffness. Is there a different graphic I have missed which says differently?

Grand Sport: Three Chassis Packages
There’s lot of different Corvette customers who use their cars in different ways, and within the new Grand Sport lineup, engineers created three options to accommodate.
Standard Touring Suspension: The base Corvette Grand Sport gets a chassis tuned for daily use and spirited driving alike. Magnetic Ride Control dampers come standard, as does Michelin Pilot Sport All Season 4+ tires and a new brake package to offer great performance while minimizing dust. “This offering is the ultimate GT, canyon-carving, road-tripping, all-out Corvette,” Holder says.
Z52 Sport Performance Package: This adds Michelin Pilot Sport 4S summer tires1, a stiffer suspension tune, and the J56 high-performance iron brake package from the Z06. “That car is meant for the enthusiast that plans to take their Grand Sport to the track,” Holder explains. “We want to offer something that’s within the tradition of the Grand Sport.”
Z52 Track Performance Package: For ultimate track performance, this package adds the J57 carbon-ceramic brake package optional on the Z06, Michelin Pilot Sport Cup 2R summer tires1, unique suspension tuning, and a carbon-fiber aero package. “This package is very mission-specific,” Holder says. “It's for the particular customer that's looking for super handling capability but wants the big-torque performance of the LS6.
