Yes, I thoroughly enjoy the Callaway Z06 w/Z07 M7. It runs well inside the coolant and oil temp limits on 95-97* track days. Ron Davis radiator and GMPP secondary radiator also installed. No trans heat issues. More usable torque available sooner (at lower RPM) in each gear.
Callaway short shifter and Akrapovic Evolution exhaust mods. What a visceral and satisfying experience!!!

Answers for your questions
1. Lots more horsepower/torque than the 2011 GS Callaway SC606 that it replaced so what's not to love?
2. Significantly cooler than reports I have read of others who track their unmodified Z06s. After multiple sessions at Lime Rock Park this last Monday I never exceeded 205* water temp and the engine never pulled timing. I will admit that it was a cool day with temperatures in the afternoon in the mid-50*s.
3. Absolutely none
4. A8 - my left leg was giving out on me after running on asphalt for 30 years in the military
5. No - basic Z06 coupe, which replaced a 2011 GS Callaway SC606 Convertible M6.
As you can see, I like Callaways (having also owned a 2005 Lingenfelter 403 Coupe) and this one, coupled with a paddle shifting transmission, allows me to track it and use it as a "grocery getter".
I obtained such a discount from my dealer, Mike Furman of Criswell Chevy, that adding the SC757 package was like obtaining it for free. I can most highly recommend Mike as I have bought two Callaways in a row from him.
I've now had my stock Z06 for a year now. I would like the conversion done to mine, at some point. Logistics is the biggest hurdle for an existing owner. The basic conversion cost is comparable to Roush Mustang conversion. Do I need it? Absolutely not! Would it be cool to have? Absolutely!

Love mine. M7 no Z07 pkg. You have to feather the throttle but it can definitely put the power down once the tires are hot. I highly recommend their short-shifter. Like others the deal from MacMulkin ($18.8k off MSRP) made the Callaway package cost neutral.
The power and torque is huge. Much harder to keep the tires from spinning. Very very professionally engineered. You can't tell it is an aftermarket upgrade.
Never ran it hard on a hot day on the track but no heat issues at all. I do run her enough that she might get hot but never did.
2015 M7 Z07. Had 5000 miles on it and almost a year old when I had Callaway do their thing.
She will be 2 years old this New Years eve. 8200 miles.
This is number 308 of all C7 Z06's built so it's a very early build. Had to take it in for a PDR update to fix malfunctioning GPS.

4600 miles.

yes. the c7 z06 stock is still a bad *** fast as hell car.

As one of those people who regularly drives his Corvette regardless of weather conditions (except for snow!) I have never had a problem caused by rain dripping down onto the engine from the supercharger opening in the hood.
Callaway installs shields on the edges of the supercharger which direct any water to the outside of the engine, away from all electrics/electronics and sparkplugs.
A8 Z07 here, with 1k miles stock and 6k as SC 757. Car is a beast with even more torque. It's pulls very hard and ran 202.3 officially and saw 205 running a bit deep past the 1.5 mark at the Mojave Magnum event in April this year. I was very hesitant to put a hole in my CF hood but now I love to watch and listen to it. I'm convinced the Callaway design helps IATs, but there are no major changes that would improve oil or water temp performance over the stock setup. That said, I would highly recommend this upgrade. It's not for everyone, but I would score the package very high based on performance, product quality, customer service, warranty and uniqueness.

Any one get the Callaway 757 for their Z06?
