Great review. Kudos for the excellent commentary re: the explanation regarding the status of the zo7 tires and alignment. Adds significant credibility to the comparison.

Thank you, Phil!

Yes we were able to experience spring mountain driving school. Fantastic! and worth the effort From Canada to get their and experience the world class instruction & facilities. Thought i had died and gone to heaven. Their staff really made the whole experience fantastic! Your site.....please keep it going, it is top notch !

Thanks for your reply. Yes i received a certificate from GM upon the new purchase. Spring mountain is totally the best place to really learn about your new corvette & acquire very important new driving skills. though it was a bit of a trip from Ontario Canada it was more than worth it & i highly recommend taking the course Thank you & keep smilin

Love that Elkhart Blue car, great video!

Skip the first 4 mins. Content starts after 4 mins.

I believe you nailed it there at the end, those Cup 2 tires must have been pretty used up. None of the other factors in this test were as important as the tires. But good fun to watch anyway, C7s on a track, what’s not to like? 😉

Did you use your Spring Mountain certificate? If not, we have a video on what that experience is like as well. You should try to get out on track with a good group that includes novice instruction, or head to Sprint Mountain for their Corvette school (although they may have moved on to the C8 at this point). Thanks for the comment, and we hope to have earned your subscription!

was wanting to see the "hot laps" !! looked and sounded like a Sunday drive to me ZZZZZZZ!!!!

Considering the two Corvettes on this list (fastestlaps.com/tracks/gingerman-raceway) achieved their times on the shortened version of the track (before the 10b extension) we figure we did alright. Of course, if you find a better stock time, we’d love to see it.

Great vid, interesting idea. I wish the Cup 2 tires had the same wear or better yet both cars shared the same tire. I would like to share what I just did. I just purchased a 2019 Grand Sport and passed on the Z07 for the reason you touched on. Carbon brakes, for a great as they are, are very costly. The Z07 is a $7,995.00 option. The stage 2 aero can be purchased from ACS Composites for $1,350.00. A set of G-Loc R-18 brake pads is roughly $650.00. You cannot compare the Pilot Super Super Sport to the Cup 2. Either way, tires ware and the money I saved will go towards the purchase of a set of wheels and R compound tires for dedicated track use.

Thank you, and your setup makes a lot of sense. We do something very similar for the track season on our Grand Sport as well. How do you like those pads?

There are variations between identical cars. At Ron Fellows they really like the Pilot Super Sports run flats.

Great video and comparison ! Did you compare the two best lap data files on the cosworth tool? It would be interesting to see if the terminal straight speeds were reduced on the z07 due to additional drag and stage 2 aero package Another interesting variable to compare the corner entry speeds considering the stronger brakes ( I.e did you overslow the car with the stronger brakes? I have a 2018 GS non z07 but including carbon ceramic brakes. I have to be careful not to brake to early or overslow the car. The cosworth tool will show where the differences are. I like your channel

We did compare data using Cosworth as well, and it was remarkably consistent. We cover the Cosworth software further here: kzread.info/dash/bejne/oYxorauaqbTRdqQ.html

When are you going to a retest with same fresh tires on both? Thanks for the review as I am looking at a grandsport to purchase. I laso got sticker shock with CF brakes.

Thanks for this comparison,i have been wondering why someone hasn't done this yet. . I noticed on the non Z07 it was in Track: Sport 1 setting. The Z07 car was in Track: Sport 2. Is there any reason for that?

@SonsofSpeed

Yes, if you turn the knob too fast and don't pay close attention, you'll skip right past Sport 1 and into Sport 2! You can get lift-off oversteer in Sport 2 where Sport 1 will intervene to stop it, but that's about the only difference between the two modes.

The 1LT doesn't have a PDR since there are no front cameras on the 1LT correct? Just the 2LT and 3LT have it I thought.

I'm in the market for a C7 GS, possibly Z06..... ummmm, how much did you say a replacement set of rotors is on the CCB?? I almost spit my drink out. How long do they last if they cost that much to replace?

@SonsofSpeed

IndividualsJasonJ yes, the list price for carbon ceramic pads and rotors is $12,000, but if you shop around, you can get it down to $7-8k (still not cheap). How long they’ll last depends on whether you’ll do any heavy tracking or not. Just street driving? They should outlast an iron set by quite a lot. We would expect the set to last between 12 and 20 track days before needing to be replaced, although the pads would probably go first. What a lot of people who track the car will do is (gingerly) take off the CCBs, carefully store them, and the put a set of iron rotors and calipers on instead. When the car is done being tracked, the process can be reversed for a fresh set of carbon ceramics.

@@SonsofSpeed thank you for the reply.... thats great info! I would just be concerned with street driving, so if they outlast the regular for street, I'm not that concerned... so thanks!

Ur time would have have been better if u brakes later with the z07 package that’s why the brakes are better to let u go faster and break later in corners u worse braking the same as the regular brakes

I own a 2017 C7 Grand Sport (non-Z07) M7. I do track my car ( kzread.info/dash/bejne/p6Zl3JSJl9q4f7Q.html ). I have stage 2 Aero and run MPSS. I really enjoyed your video and wanted to offer additional thoughts... - Aero 1 vs 2: I have been waiting to test this myself, but I have seen other videos that indicate there will be some impact to lap times, however that is track depend such as Long straights, higher speed turns, etc... - Sport 1 vs Sport 2: Perhaps it is my driving method but I have found there to be significant lap time changes between the two settings. I always find sport 2 to yield me the best lap times. - Iron Vs Ceramic brakes: the braking should not be impacted by ceramic vs iron in a few laps (i.e a 20-25 min session). the irons stop just fine. I would think breaking has more to do with the tires in this case. - Cup 2 vs MPSS - old Cup 2 vs new MPSS... that is a very wide ranging statement. I mean 4k on Cup2's is high mileage, and 16K on MPSS is high, but more important are the heat cycles. In summary, I think you video showed a very interesting and important point. The Z07 package provide in improved benefit, but the amount of improvement is tied very closely to MANY other conditions. Those who think that they will gain even a couple of seconds of lap time are deluding themselves. A total .5 sec improvement with all the same factors sounds right. Run the test again, with the same tires... frankly it doesn't matter which as long as they are the same compound. Tires are really a non-factor because both cars can be equipped with either. I considered it but in my research and comparisons the Cup2's start to get greasy sooner than the MPSS when running a full track day. They are super sticky and awesome at Autocross, but I prefer MPSS or Slicks. The Z07 package is really the ceramic brakes, the sway bars and I thought a slightly more aggressive Magnetic ride setting (which confused me when you said they were both updated to the same Mapping). Either way, GREAT VIDEO! and I have subscribed!

There’s no way the same car with more aero, upgraded suspension, lighter (1LT vs 3LT) and far superior and lighter brakes is slower around any track. 1 hot lap is not enough to be familiar with the new Z07 car especially with the CCB’s (vs the non Z07 which is your track use car). Sorry I usually appreciate your videos, however this is a fail. Try again. ;)

Chase Wingard thank you for your comment and being a regular viewer. We certainly agree with your comment, which is why we opined it should be half to a full second faster around the track with fresh tires and an alignment. While we only included the Z07’s fastest lap in the video, rest assured we spent the better part of the entire day lapping the Z07 in session after session. Safe to say, we were able to explore the full benefits of the CCBs, but braking performance is only as good as tire performance, which was certainly not at its best.

Tires are a huge part of the equation but you're driving pretty much sucks as you didn't even push the z07 equipped c7 Don't be afraid in your next video assessment

would there be excuses if the z07 was faster? no. lolol

To be honest, you're not a good track driver. You also don't understand that whether you have steel brakes or CCB, the breaking power under optimum conditions is NO different. You don't need CCB unless you want less dust or you're doing many many laps. CCB only help with heat dissipation. The do NOT have better breaking power under normal conditions. In fact, many people that track cars switch to steel over CCB because of the cost because unless you are doing a LeMan's race, most of you people would never need CCB. Lastly, learn to engine break when you go on a track. You did 0 engine breaking.

Tell us you don’t know much about track driving without telling us you don’t know much about track driving. Engine braking? That’s what you do on the street, which we’re guessing is the extent of your experience. Also guessing you’ve never driven a car with CCB brakes. They grab harder and faster than typical (non-race pad) steel. And yes, their main advantage is better heat dissipation, but having been on the end of a few overheated sets of brakes, most people would love to always run CCBs. The reason they don’t is the high replacement cost of the pads and (especially) the rotors. Were they the same price, you’d take CCBs all day and twice on Sunday.

Why do this comparison when it’s not even close to apples to apples? Old tires and no alignment vs new tires and alignment. Smh

Chet Moseley what? These places have to take the loaner cars as they get them from the manufacturer, and this was as apples to apples as you could get. You must not read/watch many car reviews because this is a common issue when media outlets get different numbers from the same cars at different times.

So run a 1:40 at ginger man and go faster in a personal car than the loaner car? I guess whatever it takes to get views. But it might be as apples as apples as you could get but it’s hardly comparable.
