Model S Plaid Track Package Waiting Room

[bhzmark]

I'm still trying to understand what about the track pack makes the car more stable at speed

I was wondering too. Mine is perfectly stable at high speed on highways; not sure how it could be more stable. Maybe the reference is to on a track with turns at speed? I would hope that is what it means but could be due to just less weight?

Is there any confirmation of any changes to the software beyond what is necessary to confirm and unlock 200 mph and deal with the different brake components? (Eg changing the trigger to show the brake temp warning light). I haven’t seen any.

The most relevant change from the CCB components should be a change in the operating temperature range of the brakes, especially at the high end, and perhaps at the cold end. Any info and experience on that would be most interesting.

Okay guys, so i dropped the car off at the sc today. After fighting with several service advisors and being given the run around on “we can’t show parts before they are installed” I was finally escorted to see what my 20k bought. All of the roots boxes looked to be in check. One tire was missing and 2 of the wheels were damaged. In the mean time they are going to be reusing my 21” wheels that came on the vehicle. At this point I’m about to ask for them to refund me the portion for the wheels and tires considering they are 5k and the tires only have 20-25 heat cycles before they die. Not ideal for street use. I considered swapping out the rubber but it does not appear that any manufacturer makes rubber in that size for ev specific vehicles. Below are some images of the boxes None of which had the pink cracked sticker (unless they peeled them off)

Hello all,
I have some information on the red/pink “Major” cracks stickers on 3 of my rotor boxes. Early on Tesla engineering seemed to grade each rotor, and use stickers. I see 23plaid boxes have some green dots. Tesla did a bunch of testing with different grades of cracking, and determined which levels are OK. I am told only good rotors were shipped as kits. I was also told the rotors have been inspected again as they put them on the vehicle. Im OK with this explanation. Nevertheless I took some close up pictures and will try and verify with ST, the manufacturer. I was also told ST does an intensive inspection before they ship their rotors.
cheers

Here is my initial reaction since it is coming from Tesla: "Cough, cough, bullshit, cough, bullshit, cough, cough."

With any other vendor: "That seems plausible."

Nice write-up, thanks. I'm still trying to understand what about the track pack makes the car more stable at speed. It's not the brakes, and it sounds like you're not using the track pack tires, so it must be either software recalibration adjusting the suspension settings, torque vectoring, etc, that's unique to the package or some other undisclosed hardware update. If it's just a software update, you'd think they'd make this available widely, as stability at speed has been one of the big knocks against the car. Did you get any insight on this from your SC?

Hello,
I too feel much increased stability at any speed. Maybe some software, but also there is about 18lbs less sprung weight on each wheel due to the rotors being less weight. Not sure about the new G wheel setup. May make a significant suspension reaction improvement IMHO.
cheers

I need someone else to check something with their brakes. Be at a complete stop and just put firm, but continuous pressure on your brake pedal and tell me what yours does.

If I put moderate pressure on it will go almost all the way to the floor. Maybe if held long enough it will. It almost feels like I have a leak.

Definitely interested in what others are seeing.

If it goes to the floor, it typically means there's air in the line(s). The first thing I would do is pop off the cover under the frunk and check fluid level in the master cylinder.

My thought is to let Tesla fix it. It is 105F in my garage right now. It was a nice 75F when I was in their garage. That is why I went with the factory install so I wouldn't "own" it.

It'll take 60 seconds to unsnap the cover and look at the reservoir. You don't want to drive it anywhere if it's low.

Nope. My pedal goes down less than halfway, then stops.

Pedal goes down a little less than half way at the most and is dead solid from there.

Lowering unsprung weight in brakes won't affect straight-line stability, unless what they mean is that they have more confidence in stopping from speed. This amount of unsprung weight loss will affect handling a little, but probably not noticeable unless you're on a track. And some of the people noticing improved high-speed stability are using the stock wheel/tire package or unchanged from what they already had on the car, so it's not the wheels/tires. Also, it may be 18 lbs total unsprung weight loss, I don't think it's 18lbs at each corner.

So if there is an increase in high-speed stability that isn't placebo effect, it's coming from something else. The usual thing that will help is aero, more downforce and less lift, but obviously that's not the case here. So I wonder if they tweaked the suspension settings and alignment so it can go lower, did something to change steering at high-speed, different bushings, or are using some torque vectoring to help.

Hello,
another notable, does it seem the regenerative braking is stronger in non track mode? I remember my wife's MX Plaid was about the same as my MS plaid, but now it seems stronger. my software version is 2023.20.9. And the track software’s now shows the 200mph, so it was properly installed.
Cheers

Thanks. Does it stop and get solid before the accelerator pedal?

To Tesla's credit, they are getting me in ASAP. I am dropping it off tomorrow to have it checked out.

Sorry to hear about your brake problem. How long did they have your car in for the installation of the CCB package? My sc messaged me saying they need to keep the car for an extra day or 2 to properly bleed the brakes.

A total of 3 days but 2 days of it in the shop. They got started midday and the install went into the next day. I think they probably spent about 12 actual hours working on it. I was their first one.

The lead tech was, and still is, very responsive throughout the process and now with my concerns. He had given me his cell to keep in contact with him. Probably the only time in my Tesla service history where I felt like I actually bought a premium car. We often like to complain but my SC has been awesome so far regarding my brakes.

That’s fantastic, Your tech sounds like my AMG tech. My sc recently did away with loaner cars and the Uber credits as well. They joked about the line at the bus stop by the dealership. My tech did tell me they work 2nd shifts so he works something like 4pm-12am. I’m keeping an eye on Tessie to watch the status. I know these modern abs modules take time to bleed properly.

Just got my Model S back after installing the CCBs, this is my first time owning a car with these so not sure what to expect. I don't plan to track the car but had them installed because I found that the stopping distance of the stock brakes don't give me any confidence when braking at highway speeds compared to other performance cars.

The tech told me when I picked up my car that the brakes will stop really well from high speeds but to use caution when driving on the street as the pedal requires more pressure than the stock brakes to stop and has significantly more travel. He said it could especially be an issue in low speed situations (e.g. in parking lots) where the car would typically stop without much pressure on the stock brakes, but requires a lot more pressure with the CCBs. I tested this briefly on my drive back and found it to be true - is this something you get used to over time?

For other owners who have had more time driving with the CCBs installed, did the pedal feel grow on you?

They've pretty much killed off loaners and sometimes you can still get Uber credits. To their credit again, they gave me a loaner while installing my brakes. The tech already set aside a loaner for me this time when I drop it off.

When I originally scheduled my appt. it was for the 2nd week in August. As soon as my service request showed up he moved it to tomorrow for when he'll be in. This is one of the few times I feel like a valued customer for Tesla.

Most of the time, you'll likely be using regen. It won't take long for you to learn to brake a bit harder. I make a habit every so often to engage the brakes more firmly to develop a feel. I will say from about 30 mph on my car, it is definitely stopping quicker than before. From that point on up it is clearly better.

I haven't tried any hard braking at parking lot speeds, I'll have to check that out. Most of the time there I am relying on regen anyway.

As for overall feel, I think while it is a bit firmer, it easier to modulate. It also feels more linear as I apply pressure. I would never go back to stock now and 100% glad I did it.

 

[Awiner]

Speaking of regen, in track mode with the regen set to 100% wow it’s like throwing out a boat anchor. I actually like the stronger regen.

Also note that when in track mode the car when stopped does not automatically go into hold. With your foot off the brake you can roll backwards or forwards depending on the slope. Double pumping the brake will put it in hold for that stop.

 

[DayTrippin]

I noticed that about regen too. I am tempted to run it in track mode all the time just for the extra regen. Well that and the torque vectoring. I wish they had a semi-track mode. Like a track mode set up for more aggressive street driving but not full on track attack.
