Was wondering if the C8 Z06 will require specific changes before a track day?

Like the c7 z51 requires a diff oil weight, alignment, metal brake o rings, etc..

Tomorrow I’ll get the manual out of my C8 ZO6 glove compartment and post a few pics of the track prep section.

Tough Crowd. I think you would still have to make camber adjustments from what I have read.

What have you read about the C8Z needing camber adjustments? No one has tested the car?
The release video stated no prep was needed for the track. The C8 was built with mega understeer/push. The Z06 is built as a track purpose car. I am not saying someone cannot find a more aggressive set of track settings - but I don’t think that is a mandatory/night and day change like the track configuration needed on the C8.

I might imagine that if a _little_ oversteer doesn't bother you, you might make those adjustments and leave them for the daily drive as well.

That's a better answer than what I gave above. I was assuming that the set up would mimic the SR but that might be a very wrong assumption.

One might consider the 2019 ZR1 track prep as it applies to this subject.

I would expect at a minimum you will need to get 1500 miles on the car and put some quality brake fluid in it. I also would expect them to provide a different track alignment spec that won't come from the factory, but that won't technically be required.

I'd expect the same rear "track only" brake ducts that the C8 Stingray has - at least for the iron rotor cars. With the CT5 Blackwing they don't provide additional rear brake cooling if you get the CCB brakes, I wonder if the C8Z will be the same way?

The C7 ZR1 is the only Corvette I'm aware of that had a different track oil spec since GM started using the 0W40. Who knows if they will recommend something special for the LT6, do we know if it comes with the same 0W40 factory fill? Other than that I'd expect specified intervals for transmission and diff fluid changes with track use and they probably will be the same as the C8 SR.

I’d put money on it, you won’t need different oil. 5w-50 is special
Not knowing camber and caster angles who knows what you may want to change and ability. A lot will also depends on a drivers aggressiveness, tire compound and % track vs street.

This is the guy I’d listen to. He knows from 1st hand experience. Be sure your high quality brake fluid is high boiling point fluid.

I'd bet money that: there will be two alignments in the user manual, and the difference between the two of them won't be as massive as it is in, say, the Z51 C8. I'll also bet that the car with the track meat on it will be pretty easy to drive without changing the alignment at all.

You have plenty of time to find out🤣. I’m sure after they actually begin production they will let us all know.

Lots of good info here, it will probably depend on how much and more importantly how hard you track the car.

The 2019 Grand Sport was probably the easiest to track out of the box, they finally put DOT4 brake fluid in it from the factory and no need to change engine oil types for track and street use.

light track use - 1500 miles required if you want an easier experience at the dealer when something breaks (ask me how I know) and follow mfg engine and diff oil changes plus add tow hooks.

Moderate track use - All the above and replace the brake pads (steel rotors) with something like Carbotech and add brake cooling ducts.

Aggressive track use - All the above and put Castrol SRF or similar brake fluid in, track alignment, swap out CC brakes for a quality BB kit or Girodisc rotors.

I will leave the harness, harness bar etc conversation for another day.

We are all speculating but I would assume GM will think it through as best they can but owners will have to add things for the track, especially hard track use. I don’t think there will be a helmet in the passenger seat when you pick the car up.

I am assuming your speaking from experience....

You won’t need to futz with overfilling the trans so that’s nice. I’m very curious if the C8 track prep suggestion to change brake fluid is a carry-over typo from the C7. The C8 comes with DOT4 now and Spring Mountain told me they don’t change the fluid… could have been wrong, but I asked two people.

The harder bushings and larger tires may allow less aggressive camber.

If you're seriously tracking the car you're changing the brake fluid pretty often anyway, so putting some srf or similar in at that point is a no brainer, as is upgrading the a more track focused pad.

My last (current) car, is a focus rs. I had no issues with the stock Brembo pads, or the stock brake fluid for hpde. But i upgraded them when they were wore out. Car also runs 5w50, and i run amsoil instead of the ford stuff, but the oil does fine. Im still on OEM rotors and they're fine. You definitely cant go around replacing rotors every time you do pads on a track focused car, you'll go broke. I did go to braided lines when i swapped the fluid, also a bit of a no brainer, if you're flushing it anyway, might as well. I haven't changed the alignment, but could probably benefit from it.

That said, i'm moving on to the Z06, because the rs just plain cant handle track days that well. The car feels tired at the end of the day, a bunch of stuff tends to overheat, etc. I'm hoping, and assuming the z06 will handle track driving somewhat better.

Definitely curious what gm has to say. I would tend to assume the z07 pack, at the very least, will come ready to track, minus a breakin period.

If you've been tracking cars you already know the little things that any car will need for track prep. What may come a big surprise how much more money you need as horsepower and speed increase. Cost will increase significantly even comparing to a C8 Z51. You can't just compare the price for a set of tires on a Focus RS vs. the C8 Z06. The C8 Z06 will use the tires up a lot quicker. You can use up a tank of gas in a 30 minute session, a set of pads on a weekend.

The biggest track prep is to ensure you have plenty of available money left on your credit cards.

Agree with the previous post, that’s a big jump from a focus to the C8 Z06 but what a fun one, you will make the transition pretty quickly.

Heavier car and more horsepower than your RS, 2019 Grand Sport would go through pads (Carbotech XP12) twice as fast as the steel rotors (Girodisc). Plan on 4 maybe 5 track days for the pads (4-5 sessions) and twice as many track days for the rotors, it’s not cheap. Tires go faster than both. Go talk to a C7 ZR1 owner at COTA and he probably had to sell a kidney for his consumables.

Not sure about the C8 but you could change the pads on a C7 in about 45 min per axle. Rotors and pads were about 2 hours per axle (I am not a pro).

CC brakes are great but you have to weigh them to check wear, most of the serious GT3 RS, GT2 RS guys swap their CC for steel rotors and swap back when selling the car.

I would love to see a BB kit for the C8 Z06 sooner than later, I am getting the Z07 package but I would prefer to track with steel rotors.

It's not just a carry over. I boiled my brakes doing a session with my son as a passenger in intermediate group. First question the brake engineers asked was whether i had changed the fluid. On my CT5-V Blackwing I had issues with the clutch sticking to the floor on track, the clutch and brakes share the same fluid and a swap to SRF fixed it.

GM may be using DOT4 but there is a big difference between fluid boiling points and what they put in isn't up to track use.
