So how exactly again is the C8 mules running sub 7min ring times?

These dinky iron rotors are not going anywhere near 7min...these mules are FAR from 7min.

Both black and silver wheeled mules are running the same base-looking iron rotor setups. They do not look any bigger than Z51 brakes and minus the vented rotors.

Do you believe the C7 aero is superior to the 488?

They go as far as putting the cars in wind tunnels to get downforce readings.
I wonder what they got with the C7 Z06?
Sport Auto weighed the 448 GTB(listed in image below):
1553kg or 3424lbs
1638kg or 3589lbs (with 75kg driver)
I got my info here:

They're not...just an internet myth.

isnt it obvious.

I'd be surprised if those test mules are breaking 7:30.

Those dinky iron rotors don't look any bigger than 350mm. A 400mm rotor fills up a 19in wheel, looks like there is 2in+ space to the wheel barrel.

They are testing the inexpensive base model C8's

Any production car sub 7:20 is on big carbon ceramics. Hell, just about all of the cars listed below 7:30 are as well.

The better brakes you have, the faster you can go... true statement...

And I don't believe those will be the production car brake package... if so, it will be a flop and slammed after any track testing.

I’m sure those brakes are sufficient...corvettes have had phenomenal brakes over the last two generations.

Let's wait until we have some track numbers to work with.

Yes, they have.
Just look at the test numbers and how it compares to others.

The C6 Z06 has 355mm(14") front rotors and in different tests, they stopped the car 60-0 in less than 100 feet. And that was with more weight transfer to the front brakes during braking than one would see with a mid engine car.

Stopping distance tests are great for what they are. But the fact is that smaller brakes will get over heated and become less effective much faster than larger brakes (especially carbon ceramic) when doing hot laps around a track. Smaller brakes can make a huge difference in lap time on a track as long as the Nurburgring even if the stopping distance tests look similar. It's all about managing the heat.

It isn't 2006 anymore. The Z07 package C6 Z06 with big carbon ceramic brakes ran a 7:22.68.

C7 Z06 has standard 14.6"/14.4" iron rotors and optional massive 15.5"/15.3" carbon ceramic rotors. They are not going backwards with smaller non-slotted rotors on the C8 Z06.

Those brakes pictured on the ME may stop the car fine daily driving, but increase distance/time during track testing will easily start to overheat. You are looking at the base C8 testing, nothing more...nothing less.

The car didn’t seem to be Sunday driving on the nordschleife to me...
I expect more rear brake bias on this mid engined car,
The CAD’s seem to show the engine being placed lower then equivalent cars.

We still have a ton to learn about this car.
I personally don’t like over engineering ....it looks very promising to me.

I read the article a couple of times and the author seems to clearly imply the C8 cracked 7 minutes lapping the Ring. Whether that's credible or not, who can say?

Oh wait, everybody here appears to be an expert with a spy drone over that track in SW Germany, I'm sorry, you guys KNOW.

I do not see any reason why those would not be the base model brakes. This is as always a budget performance car that the average guy can buy.

Brakes are very important especially at the Nurburg, that is an extremely demanding road course. Comment on the C6 Z brakes remembers that cars weight was lower than C7 and I bet much lower than the ME, weight makes a big difference on the track. Those rotors don't even have slots, holes or floating rotors which surprises me, especially how hard they pushed the car. My C7 Z51 had all those features and my Z06 was obviously much more aggressive.

not to mention the 245 tires up front.

You don't really want a lot of drama during a fast lap. To see the effects of going sideways, watch a NASCAR race. The car that gets sideways is usually left in the dust by nearby cars. If it is composed over a fast lap it means that the chassis designers have done their homework.

Why would people send him death threats over a sub 7 minute ring time. And then on the last paragraph he says

Will the mid-engine Corvette go sub-seven at the Nordschleife, finishing the work started by the C7 ZR1? I emerge from my thoughts, phone buzzing in my hand again, the voicemail icon blinking. I absentmindedly play back the message that had almost messed up my own lap time measurements.
Why would he be asking himself that if it just went under 7? He wouldn't. This article wouldn't read anything like it does.


Earlier on he says this...

I look again. It’s not a lap record, it’s not even close. And it’s certainly not the first American supercar to go under seven minutes
If it went under seven minutes, for a base model, that is VERY CLOSE to a lap record!!! And no American supercar has gone under 7, so this one is no the first makes sense in the context but differently than it may have come off.


You can't use any of this to describe a sub 7 minute time.

The lap times I’ve just witnessed the Corvette achieve tonight are simply benchmarks. They’re not serious. The car has only been on the Nordschleife for six days. It’s like taking an end-of-year school exam halfway through your first semester. Sure, it’s not a passing score, but the team will be able to look back later, development cycle finished, and see how far they’ve come.

I think he brilliantly worded it to deceive people intentionally and get clicks. Or his method of communication is Confusing.

Closer to 8 minutes than 7 for sure.

You were doing great until you got to this.

I seriously doubt this considering a Alfa Romeo Giulia QV did 7:32 flat.

Based on the tone of the article, the lap is not very fast.

You are taking it the wrong way though. It doesn't matter yet as they have only been there six days and are likely tuning suspension and logging. They are not trying to set fastest laps yet. It's not the best the car can do, more like shakedown laps. Checking where the car may bottom out, tire wear, fluid temps, etc.

None of this will matter when they put the hammer down for true hot laps.
