I will never drive my ERAY in the winter so the ZER is a option I will order. It’s not the traction etc it’s the crap roads and salt!! In my mind it’s still a summer car especially here in the upper Midwest.
Is the Z51 ride pretty complaint? How much is difference is there between a Z51 (and likely ERay ride) and a ZO6 ride?
From what:
Aaron Link, GM Exec said r.e. the suspension in an E-Ray walkaround:
it's more like the Z51 and NOT the extra added stiff spring, race car like Z06
And what Tadge amd Harlan Charles said in the Steve Garrett Podcast:
the E-Ray is more like a luxury Racer and the Z06 more for Track Rats
I say the E-Ray will be like the Z51 and the Z06 significantly stiffer. The Base and ZER Performance Option both come with MRC as standard. So ride is adjustable to some degree.
When you’re ready for even higher performance, you need the available ZER Performance Package. It comes standard with high-performance Michelin® Pilot® Sport 4 S ZP summer-only tires† as well as chassis tuning and other performance enhancements.
Can anyone tell me about the Chassis tuning and what are the OTHER performance enhancements?
From the 2024 E-Ray order guide - ZER Performance Package, includes (XFR) 275/30ZR20 front and 345/25ZR21 rear, blackwall, high performance tires and (FED) ZER suspension with Magnetic Selective Ride Control
Thanks, everyone wants to know what that chassis tuning involves? What makes it differ than say a Z51 car?
Most likely referring to a specific E-Ray MSRC calibration. It's a new combination that they've not produced before with the wide body, Z06 wheel and tire sizes, default carbon ceramics, etc. Don't forget that the base E-Ray is going to have an all-season runflat and the ZER car is going to come with a summer-only perf. tire. Each one will probably have its own calibration.

Yep, will have to wait for magazine test where they can ask.
So far we know, like all E-Rays it comes with MRC. Is the software different?? If no spring or sway bar or bushing differences still possible to match the tire stiffness characteristics. Only GM can say and probably won't until a magazine tests.
CTF cars are out. Orders can be submitted on Aug 17. That's less than a month. I hope the magazines have the cars now. Looking forward to the reviews and some more information.
According to Josh Holder Corvette Chief Engineer, RPOZER (Performance Package) optional on ERay is RPOXFR Michelin 4SZP275/30ZR20 front and 345/25ZR21 rear, black wall, high performance summer tires.
Under development of ERay Corvette Chassis Engineers determined suspension tweaks were not needed with RPOZER.
ZER is only tires.

I thought it also included the taller wickers for the rear spoiler as well. No?

I thought all E-Rays came with the spoiler extensions. Caught my Tech just when he was ready to install on my E-Ray during the PDI. Said don't bother, I don't track or go well over triple digits where they are effective. Sill have in plastic bag!

Yes, the taller wickers come with all ERays. It has nothing to do with the ZER package.

Pic is one reason I would not install (in addition to IMO they don't add rather detract from appearance.)
Bought a White 2017 Grand Sport. My prior Vettes had a somewhat "dirty rear" from the rear air turbulence. BUT that car was so bad I cleaned about every time I drove. Added a shelf in the wood column between the rear garage doors. It held waterless cleaner, rags and a small California Duster. I attributed some of the extra turbulence to the side spoiler extensions that came with the Stage 2 Aero Option (I bought mostly to get full length side skirts to block rocks hitting my rocker panels, which they did.) My Cacti E-Ray does not have that "extra dirty rear!"

Yep in a Steve Garrett Podcast Harlan Charles said the reason for a different suspension number was prior to testing is was thought there would have to make some suspension tweaks with the tire change. In fact he and Tadge said they have always had tweaks (could be as simple as sway bar bushing compliance) with a tire change and why they would say no can't just switch to C8 Z51 summer tires from all season in the base C8. They said this is the 1st time where they can say you can!
BTW having changed to Polyurethane sway bar bushings in several cars can attest you can "feel" the difference. A dramatic one was the HD Sway Bars that came with my HD suspension package in my S-10!
My 1st Pic of what I ordered the ZER Option assumed because it was a different suspension Numner "something was different." Other than tires turns out nothing was.
When between the Vettes that have been my DD since 1988, was my S-10. Bought with every HD option offered: Quick Steering, HD Springs, Sway Bars, Shocks (even a 5th Shock called a Hop Shock that reduced rear spring wrap-up on launch,) Posi. Came standard 3 inches lower with aluminum wheels, wider tires. When I added Polyurethane sway bar bushings the transient feel when taking a fast corner with significantly better.
Loved that V6, 5 speed standard trans with a number of modes, Hypertech programmer, Flowmasters etc. Would take it the fast way to town using I95. With several Vettes after will not use the Interstate. Too many 18 wheeler tire treads in the road, SUV's and Pick-Ups just driver over. Also my radar detector was always going off as a Trooper coming the other way pressed his instant on Radar. Never a beep with the Truck! But have fun taking all rural back roads to town with the Vettes. Made an enclosure for and added a subwoofer behind the center console with it's amp behind the seat!
