Model S Plaid Brakes Are Terrible!

You guys need to remember that the P Taycan EVs (and sister Audi EVs) use regenerative braking only when the brakes are actually used, unlike almost all other EVs including Tesla that uses regenerative braking simply by letting off on the accelerator. Porsche/Audi WANT you to use your brakes and quite often! I think the regular way of brake regen is better.
None, that I am aware of, have dedicated ducts like the Unplugged prototype kit. Although, in my GT3 and Mclaren, there is airflow from the front fascia into to wheel wells which we don't see on the Plaid.
I do not think anyone knows the exact percentages that regen provides. When I autocross my model 3, regen alone seems to do very little.
The only data point we have is that Porsche put brakes on the Taycan Turbo that fairly closely match the rotor/weight ratio of the 911 Turbo. So Porsche is not relying on Regen on the Taycan.

One more data point is the Rimac Rivera. It's essentially same weight as the Plaid, but has very aggressive Regen braking of 300 KW, not sure what the Plaid is, but that is 2.5x what a Model 3 Performance does.
The Rimac comes with 390mm rotors all around.
So to make better comparisons here, we need to know how much Regen braking the Plaid does.
None the less, the Puny 380mm rotors are likely way too small given the Tesla is going to make 410mmx42mm Front and 410mm x 32mm Rear Carbon brake package soon.That is a big increase, especially when you consider that width the front rotors.

I don't know if they downsized them on the 2022's but the 2019 and 2020 had 420mm front and 410mm rear,
Why Porsche Gave the Taycan Enormous Brakes
Porsche's electric sport sedan has regenerative braking, but the car still has huge 16.5-inch rotors and ten-piston calipers up front. It all has to do with Porsche's braking torture test.

Tesla Model S Plaid Track Mode coming in final OTA software update of the year - 2021.44.30 [Update]
Tesla released their annual holiday software update on December 23, packing it with a number of new features. Some of them, like the Light Show, proved popular, while others, like the new user interface, generated […]

Here is a list of all the electric performance cars currently on the market:
who knows how thick the rotors are, hat size and regen.
| Rotor Size (mm) | Curb Weight (lbs) | Rotor/Weight ratio (higher better) | Rotor Material | Horse Power | |
| Audi E-tron RS GT | 408.94 | 5137 | 0.0796 | Carbon Ceramic | 637 (boost) |
| Porsche Taycan Turbo S | 420 | 5101 | 0.0823 | Carbon Ceramic | 750 (boost) |
| Rimac Nevera | 390 | 4740 | 0.0822 | Carbon Ceramic | 1914 |
| Tesla Model S | 380 | 4766 | 0.0797 | Steel | 1020 |
| Lucid Air P | 386 | 5050 (R) | 0.0764 | Steel | 1111 |

Added the track pack carbon ceramic rotors for the plaid and kept the curb weight the same:

| Tesla Plaid | 380x32 | 4766 | 0.0797 | Steel | 1020 |

Well done. Looks like the Track Pack now has the best Rotor to Weight ratio!
I compared it to cars designed to go on a race track.
The BMW i3 is 0.0844, which is higher than all of these and not a car I would want to compare it to. It has 184 hp and regen.
The Taycan GTS is being promoted as a fun canyon and occasional track day car and that car has 360mm front rotors with a curb weight of 5077lbs with a ratio of 0.0709. I am comparing the Plaid to similar high performance EV's. I feel that the UP front rotors and track pads that I ordered is more than enough for my needs when looking at the table. I think I am going to leave the rear rotors alone but I am not sure what to do about the pads.
You are comparing relative similar weight cars that have 1020 hp vs 562hp. The power to weight ratio of the Plaid is double the GTS. The speeds the Plaid can achieve are quite different. That is like comparing the rotors on a Corvette to a Miata.
That's why on the table I have similar hp and weight cars. The GTS was a reply to your comment "I compared to a car designed to go on a race track".
I can run my Plaid at the track on sport mode aka "Taycan mode" to not cook the brakes lol.

Yes, Interesting to note that "regenerative braking power is strengthened to recover more energy."Track mode is here
That's possibly my favorite Track Mode feature. It's great when tearing up a twisty back road, you can maintain a much faster pace while minimizing use of the brakes. More efficient and feels better.
When you've been driving with Track Mode max regen for a bit, and then switch off Track Mode, you'll feel like "Where'd my regen go??"
Edit: Track Mode max regen in the M3P also makes the accelerator mapping feel smoother and more linear by using more of the pedal travel for regen. In normal driving mode the M3P accelerator mapping is too jumpy for my taste. (I imagine it'll have a similar effect on the Plaid but I haven't driven one yet!)
