I boiled the fluid in my C8 Stingray just running around in intermediate group with my son. I got a warning light on the dash and after that the pedal felt wooden. The first thing the engineering team asked was “did you change the fluid before you took it to the track?” There is a reason they recommend changing it as part of track prep.

Similar. It probably comes down to a number of factors like my not so good braking skills, but I have had similar experiences at Thunder Hill, Laguna Seca and Las Vegas Motor Speedway (the outside course). It is absolutely terrifying heading into turn 8 at Laguna and have your pedal go soft. I know some guys have great luck with OEM equipment, but I just have not. I bleed regularly and flush once or twice per season depending on how much I drive. And when I bleed the brakes, I run through a LOT of brake fluid. It's probably a waste but it makes me feel better. I probably change my engine oil way to often too, but again I figure its better than a repair bill.

Thanks for everyone who contributed to this thread and big thanks to Michael Palmer for putting it all together for the following article.

https://www.corvetteforum.com/articl...st-sports-car/

Let's keep the conversation going, the questions, answers, impressions and opinions. I figure there are no stupid questions. None of us know this car. Not even me and I have one in the garage as I write this! I also figure what we think today is likely to change as we learn more. Right now my impression is based mostly on very sedate driving on public roads. Once I get a few long sessions (15 laps or so) and I get a sense of how the car (and driver) work under stress, I bet my impressions are different.

Speed Ventures has Button Willow on December 17/18. Let me know if any of you are planning to go - would love to meet up and compare notes!

A couple questions. Was the car ordered "for the dealer" and they sold you the car for MSDRP plus ADM? If you do not mind sharing, what was the ADM.

Regarding the car. I find the C8 Stingray a bit underpowered but comfortable for the street. The challenge is to find a car for the street that is enjoyable only compromised for those who do not have a dedicated race car and need the car to do double duty. When speaking of "street" car comparisons,, I think of the Ferrari 458, not as fast as some, but perfect gearing and more than adequate power for the street. As I read you excellent presentation (appreciated), it occurred to me that the Z06 might be a bit much for those who do not track a car. Back to the 458. This car's shifting points and power permitted ease of driving and a great flat plane sound. By contrast newer Ferraris, rev to quickly for my comfort and create too much work. When thinking of the Z06, I wonder if it is not the reverse of the GT3RS.
The Porsche is a race car ill suited for the street because it cannot be enjoyed and driven comfortably on the street, while the Z06 appears to be a car designed for street use but has a little bit too much track in it, requiring self control when driving and finding revs coming up and shift points a bit uncomfortable.

How do you find the street driving. Unrelated, what is the opinion on tire wear when resetting camber/castor/ toe in, etc?

I am #86 on list at Les Stanford Chevrolet and #6 at a smaller dealership.
I face the possibility of being asked to pay $50,000 to get #6 early or wait an estimated year to get #86 at MSRP.
The good news and I was lucky was to find an available slot to order a Cadillac CT5-V Blackwing about 3 weeks ago which should arrive mid January.

Same here. I'm pretty sure even the annual bleed isn't necessary, but it's worth $120/year to not have it in the back of my head.

Thanks for taking time to give us a write up! I was never considering the Red Mist....but I gotta be honest that looks pretty killer in that color combo!

I ordered the car through a local dealer. I have zero experience in a C8 so cannot speak to the power differences, but I like carrying mid corner speed where HP is not all that helpful (sometimes even hurts me), so HP is not a huge consideration for me. Some of my fastest friends drive lower HP cars and carry insane mid corner speed and are really, really good on the brakes. The Z06 does rev incredibly fast, and I am not yet used to it. I do street drive it a lot, and am learning how to quiet it down (or I am losing hearing). Even so, it lugs around pretty good under 4,000 RPMs so for me it is very streetable.

Right, I'm talking about those owners who don't track and wouldn't want to live with the "downsides" of higher performance fluid being the reason GM doesn't do it factory fill.

That would be amazing! Or like when you get close to home, and you do not want to wake the neighbors. There are actually quite a number applications for this idea.
There is an aftermarket solution like what you describe for Porsche. Closes the exhaust valves based on user programmed GPS locations. As far as I know, no one has made a similar system for Corvette C7/C8.
