The C8 Corvette Z51 has been the fastest production car we've ever tested. Can the Z06 beat it, and by how much? We took one to our test track, the FIRM, to find out.

That fact that my ass owns a 2024 Z06 Z07 is amazing. Bought it a week ago with 18 miles on it. I was the kid everyone bullied in middle school, passed highschool with C's. Did a 4 year contract in the Army. Got out and was broke my whole life. Got a decent career 4 years ago at 30 years old. Now I own a newly built home, and a Z07, and the biggest blessing is my big booty latina wife and beautiful child. God bless the USA, (and big booty Latinas)

And think about this: I had hundreds of laps in the C5, and maybe 10 flyers on the C8. I can look at that data trace and clearly see areas where I'm losing time due to driver error and not car limits. So I had probably another .3 in the C8 as it sat. Now throw an alignment on it and actually pay real attention to tire pressures and how much faster are you going. The thing is an absolute monster.

The Z06 gains some weight from additional coolers and cooling fluids, but loses it due to light weight wheels and brakes. For similarly-equipped cars the Z06 (with carbon wheels) is only around 30 lbs heavier than the Z51.

Ultimately, GT3 programs are as much about support as they are the car product. All the cars-which tend to be developed by contractors under varying levels of factory guidance-usually end up with similar performance and reliability levels due to BoP. So what ends up separating them is who has the best support after the purchase. Which manufacturers have the best equipped parts trucks in the paddock, and the fastest turnaround times for customer needs. It's been a looooong time since chevy had a non-factory Corvette program, but I'm certainly looking forward to seeing how they attack the GT3 marketplace.

We'll respectfully disagree a bit on this. we found the handling of the C8 to be extraordinarily benign at the limit. Maybe even *too* benign. Particularly in long corners where the front gives up long before the rear and you spend the last 2/3 of the corner just waiting for the exit to open up. Certainly things are happening very quickly, but we found the overall drivability of the car at the limit to be exceptional.

@@Grassrootsmotorsports I can respect that. Maybe it all comes down to setup. There's a vid circulating of a driver at NJMP (My neck of the woods) who was struggling to keep things civil. He drives respectable laps and is pretty competent. The car just seemed oversteery and ass-endy and that's a very unforgiving recipe for the uninitiated. You know that game we used to play as kids at the dinner table? When you would balance your chair on two legs.... then right before you fall backwards you save it? The C8 Z06 appears to be very much like that. Keep in mind that your test track appears to be flat with minimal elevation changes. It's smooth, and the curbing isn't such that would disrupt the car's stability. With all that said, obviously my opinion accounts for very little since I have not had the privilege of thrashing one. But with 20+ years on track I do trust my intuition that the C8Z will not suffer fools or your typical track rat who cannot save snap oversteer. If you have the car for some more time, try a rollercoaster track like Road Atlanta and let me know what you think.

What driver mode and PTM settings were you using? Are you able to put power down on corner exit without excessive wheel spin? I have the base ZO6 and replaced the 4Ss with regular Cup2s and constantly struggle with oversteer on corner exit no matter what PTM settings I use. It seems PTM is not working even in Sport. My C8 lap times on R7s are actually better at this point, which is a huge disappointment. Any ideas? Other a stiffer suspension settings and aero are there any other performance differences between the ZO6 and ZO7?

We use as little intervention as we can tune in. For this car i think that meant there was almost zero traction management (I did a pretty solid burnout to test it), but I did feel a tiny bit of front wheel brake intervention on a corner exit at one point to stabilize the nose. Didn't see to lose momentum, though, and I' not sure you can turn that one completely off, anyway.

Possibly tire-related? I’ve found the PTM to be very conservative (slow) to provide power on not hot tires (like 3 full laps on R7’s), especially at tracks like Mid-O and VIR where the surfaces are well-traveled. At Road America where the surface is new, 1 lap and PTM says Go!

If you look at the data you can spot some areas where it's kind of easy to make some extrapolations. Also, we kind of know what tires are worth on our test course by now, but let's go back to the data. If you look at areas of pure cornering you get a pretty good idea of how much more grip the tires are producing. braking can be deceptive, because remember the Z06 is approaching the corners faster so it has a LOT of additional energy to convert. The tires help do that more efficiently, but energy is still energy and needs to go somewhere. So I think what you end up with is the better lap time is about 40% power, 40% pure mechanical grip and 20% chassis control. Like, that run through the esses is purely abut shock control. More grip or power doesn't affect that section as much as great shocks do. So I think the C2Rs on the Z51 would be worth 1.2-1.4 seconds. Which is in line with what we see in our tire testing on project cars.

Short answer: yes. Longer answer is our test track may prioritize the point-and-shoot ability of the C8Z, so on our particular track it could be a close match. On a faster track the GT3's more extensive aero and longer legs could give it a better shot. At any rate, we think we may be able to find out soon. Stay tuned :)

When does the aero wing kick in. When does it make a difference. Speed?
@Grassrootsmotorsports
@Grassrootsmotorsports Жыл бұрын
Even at low speeds, aero has some effect on localized pressures. But remember that drag (and therefore aero effectiveness) increases by the square of the speed, so higher speeds mean more downforce, and the difference ramps up dramatically. that said, even 40lbs of downforce in a 40mph corner can alter handling balance enough to make a measurable difference. is it going to be giant chunks of time faster in slow corners? No. But it might add enough stability that your lap-to-lap variance in slow corners is much more consistent. That said, above about 70mph you can definitely feel the car enjoy a lot more stability from the aero bits. Particularly in the kink, where both C8s are among our fastest cars through that section.

@Grassrootsmotorsports
@Grassrootsmotorsports Жыл бұрын
By "accessible" I'm really referring to the amount of performance potential the driver is able to extract from the car. It's a very easy car to drive fast, turning novices into experts and experts into heroes. As for actual availability, well, we all know the current dealer and market climate. Last I checked dealers are still getting $50k over list for Z06s with a year wait, but that's better than the $100k over they were getting when they first dropped. And, ultimately , it's a mass-produced car by a huge company. I like to think that there's a future where if you want a Z06 that one is available at a dealer within a few hours drive at or near list. I'm not sure how far away that future is, but hopefully it's coming. Not that I'll have 4150k to drop on a car then, eight, but it's nice to dream. As for the Cup2Rs, I can't really comment of overall lifespan, but I can say that in our testing, we usually find that track-focused tires last longer on track than pure street tires. They may have a shorter overall lifespan, but they handle abuse and extreme dynamic heating better than a tire that also needs to do daily driver duty. Our test car had just come from a full weekend at Sebring where the driver did like half a dozen track sessions, as well as driving to and from the track, and to and from our test day. The tires still had plenty of grip and predictability, and had about 1500 street miles on them as well. It's a fast, heavy car so it's going to use tires at a fair clip, but it doesn't appear to be unusually abusive to them.
