Some other C8 Z06 fun facts from the Bash, not covered above (plus a few related to the C8 Stingray):
1. the Z06 oil filter is different from the Stingray: it's a canister in a housing (it doesn't screw on) since the original versions gradually unscrewed due to the flat plane crank vibrations.
2. the transmission on the Z06 is also different than the Stingray: it's similar but there are about a half-dozen differences. I can't recall all of them but do remember Josh Holden saying the Z06 transmission had a thicker housing and an extra plate in it. Sorry but he rattled them off so quickly, I can't remember all of the other differences. Unfortunately I didn't ask if the Z06 will use the same transmission filter(s) as the Stingray. So many questions...
3. the exhaust system on the Z06 can be adjusted, so upon start up, it doesn't have a loud "bark" if that's the setting you choose. That differs from the Stingray which has the same "bark" upon start up all the time. Unknown if the Stingray will be adjustable for 2023 (it didn't come up).
4. Mobil 1 is renaming it's oil "Supercar" and that will be for both the C8 Stingray ESP Dexos 2 0W-40 formulation (the same oil renamed), plus the new 5W-50 oil for the Z06. They were originally going to name it "US Supercar" or something similar until their Canadian reps complained and pointed out Canadians were or would be driving these same vehicles with Mobil oil in them. The Mobil reps made it clear that you shouldn't be driving your C8 with the European Mobil 1 formulation although one oil change with it shouldn't hurt anything. This Supercar oil will be available first to dealers and the NCM. After that, retailers will be able to get it and with more and more people buying C8's, they expect more retailers to start stocking it. They had COVID-related supply problems but those have now all been ironed out. Someone in the audience asked during the Mobil 1 presentation, if it there was a life expectancy for the Corvette Mobil 1 oil. They said it could last up to 10 years but they recommended you change it every year, as per GM's recommendation. So as always, they deferred to the vehicle manufacturer on when to change the oil. They discussed a fair bit the benefits of the "Supercar" oil, pointing out it was specifically formulated to avoid moisture with that same moisture being very bad for a high performance engine.
5. the Z06 visualizer isn't showing the correct brake caliper colors. It's unduly restrictive so for example, right now it shows a gray caliper whenever you choose the ceramic brakes. So it has some kinks that have to be worked out.
6. you can buy the Z07 package with the 70th Anniversary Edition of the Z06, plus you can eliminate the body stripes on the car (get it with or without those stripes) but other than a few changes like that, you have to take the Anniversary Edition as you see it, in either the Pearl White or Carbon Flash colours. You can get the Stealth interior package with the Anniversary Edition plus the Carbon Fiber Interior Level 1 package (on either Stingray or Z06 versions). But you cannot get the CF Interior Level 2 package in the Stingray Anniversary Edition; only the Z06 Anniversary Edition. You CANNOT get the carbon fiber (CF) rims with the Anniversary Edition: it only comes with the one set of rims with the red outer edging. Those same comments apply to the Stingray.
7. for those buying the CF rims, the car will come specifically set up for them, due to their reduced weight. I asked a GM rep if that meant people buying the Z06 with the Z07 package and CF rims, then putting on a second set of rims (aluminum) would have to go to a dealer to recalibrate the car. I was told no dealer could do that: a dealer will bring up the original car codes and only be able to set it up based upon those codes. GM would be able to recalibrate the car, but not any of its dealers. And running a set of aluminum rims on a car calibrated for the CF rims, wouldn't hurt anything so they suggested that was the way to go and it was better to use aluminum rims on a Z06 set up for the CF rims...than use CF rims on a car originally set up for aluminum rims.
8. the new carbon ceramic brakes produce next to no brake dust and are really effective, even when cold. That said, they get better the more they heat up. They'll last a lot longer with track use and for street use, they could be the only set of brakes you'll ever need. Having said that, they're likely to be ++ expensive.
9. the Michelin reps confirmed there were no Z06 tires for sale on the retail market now. There were some winter grips (Alpin Sport) but GM bought them all. I can attest to that since I found Tire Rack had some winter grips a few months ago, but now they're long gone. Michelin expects the winter grips to be available fairly soon and an all-season version might be out in about a year (?). These were just estimated times.
10. the "Stealth" interior option when viewed in person, didn't look like the Visualizer. Whereas the Visualizer made the speaker grills (on each door and the top between the seats) look quite dark, in reality they were a slightly darker shade than the original "silver" look: I'd describe them as a "burnished steel" colour. The trim under the dash was noticeably darker than the original though. These comments apply equally to the Z06 and Stingray.
11. GM does NOT recommend you change out the Z06 20" and 21" rims/tires with larger 21" and 22" aftermarket ones (for example). The OEM tires/rims have been tested specifically for the Z06 and matched to its performance characteristics. Maybe all manufacturers will say that about any vehicle they make, but the Z06 is very performance oriented so perhaps this is good advice. Something to consider.
12. the base Z06 will come with a set of "wicker bills" in the trunk, which can be added onto the rear spoiler if desired by the buyer.
13. the break-in period for the Z06 is the same 804 km/500 miles as the Stingray. I think this was released previously but it was brought up at the Bash.
14. (new: May 2) it was previously announced that the Z06 would have magnetorheological motor mounts, being motor mounts with fluid containing a suspension of magnetically soft particles in a synthetic hydrocarbon fluid: with computer-input, the magnetic field is varied to dampen vibration. This was thought to be a ++ improvement for the Z06 due to the increased vibrations inherent with a flat plane crank engine. At the Bash, it was announced that the Z06 would have "standard" motor mounts and the previous reference to magnetorheological mounts was due to a misunderstanding (whatever that means). Oh well; I suppose the up-side is omitting that new technology, should improve the Z06 pricing.
15. (new: May 2) Josh confirmed that if you buy the CF rims on top of the Z07 package, you'll receive the CF rims (only) with/on the car. You won't get the regular OEM aluminum rims since the CF rims are a replacement rim and not an accessory rim. Hopefully GM will factor in the price of the aluminum rims that go with all the Z06's, when deciding what to charge for the CF rims.
16. (new: May 4) when it comes to Z06 brake caliper colours: when you order the Carbon Ceramic brakes (“J57”), Harbor Gray is standard; options are Bright Red, Edge Red, Edge Yellow and Edge Orange; then for the regular cast iron brakes ("J56"), Black is standard; Bright Red, Edge Red, and Edge Yellow are optional.
I'll list more as I think of them; there was a lot of info in a short period of time. Hope this helps.
(new May 4) PS: although not discussed at the Bash in my presence, CorvetteBlogger found this out at the Bash: if you want the High Wing on the 2023 Z06, you MUST order the Carbon Ceramic brakes. I suspect this will be a boon to aftermarket sellers of the High Wing due to the cost of the CCB. The CorvetteBlogger article is here:
We got some clarification at the NCM Bash for ordering the C8 Z06's High Wing Spoiler which requires the addition of Carbon Ceramic Brakes.
