Historically from what I understand the Z07 package have not included adjustable sway bars, and they have not included non-compliance/spherical bushings in the suspension.


The 1LE package on the Camaro ZL1 includes: ball-jointed rear toe links and stabilizer bars (in other words non-compliance/spherical bushings) , front camber plates, adjustable sway bars and DSSV dampers.


What are people expecting in regards to the suspension on the C8 Z06 and the optional Z07 package?

No modern OEM Corvette has had adjustable bars or anything other than rubber control arm bushings for NVH mitigation. One track acquaintance went from a C7Z to a ZL1 1LE and back to a C7 because the 1LE was so harsh on the street. That car is special because Al Openheimer (sp?) is a track nut and was in charge of the Camaro platform at the time.

I suspect the Z07 package will be similar to the C7 with increased spring rates to accommodate the aero, revised swaybar bushings, and unique MSRC shock tuning. I don't see them getting into non-rubber bushings, adjustable bars, or going away from the mag shocks.

From the multiple people I have spoken to that have driven in and/or owned a ZL1 1LE, they have all commented that the car is absolutely horrendous on public roads. Harsh is probably putting it lightly!

My guess is compare the "Z07" package on the C7, and you'll get a pretty good idea.... but given that neither car has been announced, its pretty moot at this point

vndkshn

Per NCD it will have whatever the C8R racecar uses.... just minus stickers.

In seriousness, I could potentially see the Z07 add-on package coming with a NVH penalty. Don't think I'd want spherical bearings, but some upgraded poly/delrin is livable.

With as much critical success as the ZL1 1LE has received, and given the purpose of the Z07 package, I could see them adding the DSSV dampers to that package.

NemesisC5

One of the online sites, I think it was GM Authority had it rumored the DSSV dampers would be one of several stand-alone track focused options to be available. No speculation on my part....only something I read, just waiting to see the real deal whenever that occurs.

Z07
- Carbon ceramic brakes
- Most aggressive aero
- Pilot Sport Cup 2 (or equivalent) tires
- Reduced ride height
- (Possibly) carbon-fiber wheels
- Unique suspension tuning to account for the aforementioned changes

Doubt we'll get DSSV dampers, the in-car adjustability of the magride really helps to smooth out a stiffer spring for a dual-purpose car. I think they'll target the Z07 for the track but they realize it'll be street driven as well. My Z07 is incredibly stiff in track mode, way too stiff for even smooth city streets; I'm in tour mode everywhere on the street. Plus the magride damping can be updated by wire if needed.

The eccentrics will stay; I'd like to see Delrin/poly just to take away some flex and lessen the camber variation, but I expect to see the usual soft bushings. CC brakes, wheels, stiffer, different mag programming, aero.

JockItch

It all depends what they want this generation of Z06 to be. If they are truly going the NA FPC, track focused route, I could see them upping their game for their most extreme track package. Making the Z07 package more akin to a GT350R or a GT3RS. The Camaro ZL1 has mag ride suspension too. It’s still a very capable car, and the one for the masses. The ZL1 1LE package isn’t meant for posers, its meant for those that frequent the track. It’s brutal on the street... but thats not its purpose. Lack of compromise is what makes it special.

Iker

It depends on their goal!
if the goal is developing track car, they will go with with DSSV
if the goal is developing a street car with track capability, they will go with MRC
But as far as I know corvette is always meant to be a street car

You can buy a ZL1 with a soft mounted MR suspension or a ZL1 1LE with a hard mounted DSSV suspension. It's just an option, not a different car. Why can't they do it for a corvette if they do it for a camaro? The $7,500 1LE option bought the ZL1 1LE 15 seconds at the ring. That would put a C7Z under 7 minutes. The marketing alone would be worth the offering. It's not like they'd lose any money offering it. GM would actually be making the money the aftermarket would from people modding their Z06 suspensions.

OnPoint

If I had to guess, it'd be that we see MR shocks on both the Z06 and the Z07, although I wouldn't be shocked (pun intended) if we see DSSVs on the Z07.

That said, I'm actually a bit concerned about the commitment of GM to further the performance and line-up development of the C8 given the amount of talent they've poached off the Corvette team and reassigned to the EV program. My hope is that the line-up sees robust development and that we see a solid Z, followed by a great ZR. In the past, as a ZR customer, I've taken that a bit for granted. But at this point, I'm simply praying they actually build a ZR given the current direction of the company and the talent drain forced onto the Corvette team.

RapidC84B

Did they actually reassign those folks? Or did they just move the C8 team under a different umbrella? We all know and electrified/hybrid C8 is coming.

OnPoint

What I read said reassigned. But, with any reporting today, it's probably best to take the attitude of reading it and then thinking, "Gee, what if that were true?"

Losing Ed Piatek's and some of his crew's focus on the Corvette gives me pause:

But - I'm hopeful the commitment to finish out the engineering and build of the perf variants remains, and is far enough along that they get done.

And I definitely see them pushing at least a hybrid variant (on the electrified path), given the direction of the company.

jcp911s

This means nothing.... I worked for AT&T.... later Verizon.... we were constantly being moved from project to project based on workload... I'd guess 4 years ago, the C8 team was working 100% capacity.... the car is done.... they don't need these people right now... put them to best use...

RedLS6

I think even the track rats need to be careful when deciding on a potential DSSV option; for me, potentially doing 10 track events per year at an instructor/advanced level, and also wanting the Z07 option, there's no way I'd check the DSSV box on the options sheet unless the performance damping characteristics and rates are substantially changed....and then, how well would it work? For a pure race car, it may be a different decision for me. YMMV, and they still could offer it as an option. My main point is, there are probably a good number of folks out there who think they want this option, but don't realize the tradeoff.

waltk88

I’d like so see carbon ceramic brakes as an option on the Z07 package and not mandatory. I plan to track the car about once a month and don’t want to chew through expensive carbon rotors and pads twice a year.

RapidC84B

Agree... carbon brakes are not for me.

JockItch

I’m hoping they are a stand alone option regardless of Z07 package.
