I am going to trade my 2015 ZO6 in for either a 2018 ZR1 or a 2017 Callaway SC757. I would like more horsepower for the track. I live in south Florida and track the car at Daytona and Sebring. I have a M7 and although I have not had limp mode, I have had decreased lap times as the car heats up. I would like opinions about cost vs performance and value.

ZR1 hands down.

The Callaway and similar packages are nicely done, but still a modified car.

The ZR1 will be the most complete C7 imaginable with a few years of solid engineering behind it.

Depends.

If price is an issue and assuming you can score a Z06 at 20% OFF MSRP I think the Callaway may be one hell of a bargain. Think 3LZ for $73K + Callaway for $18K = $91K net. 660rwhp from recent dynos and a warranty make it a good buy. Also assuming the ZR1 will be $130K, $39K in your pocket can fund a lot of HPDE's and consumables like tires, brakes, fluids, etc.

If price is an non-issue, absolutely get the ZR1. It will be bad ***!

Since I've seen the new ZR1 in action at Laguna Seca, I can attest to the potential performance upgrade. The ZR1 will dominate just about anything out there on the track and that includes the 918 and the P1 which have been upstaged by the Viper ACR recently. The Callaway may be fine for straight-line but will never come close to the new ZR1 on a racetrack. The ZR1 cornering speed that I saw at Laguna Seca was eye opening.

This.

I think you have time to make a decision. I suspect there will be a few 2017 Z06s on the lots come August/September when the ZR1 hopefully arrives.

I'm in the Z06 market and not the ZR1 market, however between your two options, I would be leaning towards the ZR1 based on what I've seen and more importantly, heard.

I wouldn't be surprise if the ZR1 carries around the same horsepower as the Callaway and be pretty much the same at the track. However, there aren't enough Callaway cars out on the track to prove any point for right now. Although Callaway is a modified car as mentioned, it still carries the 3 year warranty. If in fact money is not the issue, then go with the new ZR1.

I think it all comes down to what you want. If you want a Z06 with more power that still has a warranty, then the Callaway is the perfect choice. If you want a track car, the ZR1 will be your best choice since it will already have cooling, aero, and suspension ready to go (not saying the Z06 is in terrible in any of those aspects, but the ZR1 will be better prepared).

G fix needy

There are still a lot of unknowns.
1. Unless a track with really long straights (like the 'Ring) is available in your locale, a Z06 with the new nose/cooling package & wing, if available as an option, may be the way to go.
2. If not, or if it has to be the fastest available anyway, it's simple - ZR1 (with at least 750 hp hopefully).
3. Or if not, a Callaway 757 with new nose/aero/wing???
4. If it's mainly for the street, a Z06 or Callaway

IF the mission of the car is THE TRACK, then the ZR1 is the clear favorite.
IF it is street duty, then maybe the Callaway might be a better choice.
Of course, YMMV.

bcmarly

For the ZR1 to exceed the performance of the P1 & 918 at the track it's going to have to have a few tricks up its sleeve. Do you have any insight? - hope you're right.

The Blue Beast

Price matters but it is really about if the ZR1 will be that much better performance wise on the track, that it is worth $39k difference . I street and track my car but ultimately I will compromise streetability for great track days. I am just thinking that the Callaway will have slightly more horsepower and would likely not track as well but maybe be a minimal difference on the track. Opinions ???

Z0HS1CK

If those are your 2 options, definitely the ZR1.

However either car will be too much for a novice driver anyway so is getting the ZR1 really worth the extra 39K??

It would seem to be more about bragging rights than to get good lap times at whatever track you're going to.

Both cars will perform just as good to YOUR skill level, saving money on the callaway would be the wiser choice.

But the ZR1 will be more of badass choice.

Choose your poison.

cvp33

The Z06 will crush 90% of everything we see at an HPDE. The ZR1 will be better. $39K better? No idea until we see one in the wild.

Either option would be good but I would check with Callaway if they are still releasing a cooling pack and when. Once they mentioned that they are working on a Z06 cooling pack for track duty.

sunsalem

The Callaway doesn't have an army of engineers to maximize the increased aero efficiency we all expect the ZR1 to have.

BTW, we don't know the power rating of the ZR1.
Most expect it to at least equal the Callaway in that regard.
Agreed, but we still haven't been given a price on the ZR1....$39k seems a bit too much IMO.
$20-25k would more reasonably fit into the Corvette demographic.

5thGear

I hope it's not a ZR1 and it's just a Z06 1LE. Maybe just 10k over Z07.
They will sell a lot more to track enthusiasts that way instead of high priced ZR1. For ZR1, there should be a major change and I don't see that in the test car. It looks like a Z06 with track updates. Basically an ACR version of the Z06.

Frans96ss

We had a callaway 757 package car on my dyno and it made the exact same as another one stock c7z. Both manuals. 757 car made 584. Simply terrible

four0nefive

That's odd considering the Callaway is SAE certified on an engine dyno to make 757 HP. Maybe something wasn't right?

cvp33

Interesting. The one at Vengeance Racing made 658rwhp. Sounds like you got a dud.
