Has anyone had any experience taking their car to a track day without making the recommended alignment, brake fluid and oil changes? My Camaro ZL1 could go back and forth with no changes (as could the C6). I am curious if anyone has tried the C7 as is.
Prepare to ruin a tire. I did a mere autocross day and significantly wore the outer tread of my left front tire. If I had the recommended alignment I believe the tire would have wore evenly.
I may go in a month...I'll have 25% oil life left, I already changed to Motul brake fluid.
I gather we should check the torque on the wheel lug nuts.
I am interested in the recommended alignment specs.
Going to do a Skip Barber class at the same track before I attempt my first track day with my C7.
Allow me to answer this from the Right Seat (Instructor View); NO, you do not need to do a track alignment to go play at a HPDE.....especially if you are a novice/beginner. Brake fluid should be fresh but not necessarily the high buck high temp stuff and here's why.
Your first or even sometimes your second HPDE event, you are still learning basic skills just to get around the track safely. Just because you're driving a very high performance car doesn't mean you will be turning qualifiers right off the get-go! I like to equate learning tracking to playing golf; your first time out to a driving range do you really expect to grab your "Big Bertha" and smack that little white ball some 400 yards in a straight line?....it ain't going to happen. The same holds true for tracking; just because you have been "Street" driving for many years doesn't mean you will do well at the track.
It takes lots and lots of practice getting the basics down before you need to start making changes to your car. More on this later, got to go to dinner.
^^ Pretty much this, I have tracked my car stock, temps all stayed fine, brakes never faded, still have the same tires on the car with 20k on them. I have done the Spring Mountain class and 2 HPDE days so yeah, the car can take what little damage I can do to it stock (Z51)

Reason: No need tore-quote the previous post, especially if you're the next person posting.
^^^^ Please, What is "upgraded engine oil" other than fresher Mobil 1?
Thanks to earlier poster response with the alignment specs...much appreciated. I have a local buddy with a Z51 who tracks and will confer with him as well.

I agree with the comments that if you're a novice you don't need to do much. However I would absolutely put the 15w50 weight oil in as specified in the owners manual.
Good info....thanks
Are these specs the same with a base 18/19 wheel and a I9/20 wheel size?
I have a base 18/19.
The DSC specs posted above are recommended for both Z51 and Z06 w/ a much greater difference in wheel and tires sizes, so I'm pretty sure they're equally good for the base 18/19 wheels and tires. All C7s are riding on the same chassis.
The CEO of DSC Sport is a world-class race driver and previous winner of the Rolex 24 Hours of Daytona. He also owns a Z06. Those are his specs.

I agree with this. Even as a novice you will be running the car harder and longer than you would on the street. Up until the C7 came out GM recommended just running the standard street fill for the C5 and C6. The recommendation in the OM may have come from a lesson learned from warrantying many engine failures that might have been avoided with a higher viscosity oil. Why would they tell you to run 15W50 M1 and remove it if it didn't do some good.
Do the oil and the brake fluid and leave the suspension alone to begin with.

So do you have drain the oil when done at the track and go back to the 5W30 or can you run the 15W50 all the time?

I basically agree with this, but a proper alignment for a C7 (I chose "street/occasional track") makes a difference even if you're only going to drive on the street. The C7 alignment settings out of the factory are all over the map, according to Mike Levitas, CEO of DSC Sport. He told me they don't actually align the cars before they leave the BG plant, claiming the equipment they use to bolt the components on produces cars within "acceptable specs."
My car was noticeably better on the street after the alignment posted above, and for $300-400 at a really good alignment shop, it's well worth it.

It's interesting that the owner's manual does not say. The service manual often has more information about approved oil viscosity for different temperature ranges. My guess is that 15-50 is fine for warm weather, and the service manual typically gives the temperature range. The owners manual usually shows the lighter oils, because they want people to run those for fuel economy.
