So is the "base" Performance model without the Performance Upgrade going to have the same brakes as the standard RWD and AWD models?
I hacked on the compositor to generate a couple of images at the highest resolution, one with 19" wheels and one with 20". Who knows if the compositor is even remotely accurate, but I found:
rims 484px / 19in = 25.47 px/in
rotors 334px * 25.47 px/in = 13.11in (333mm)
rims 507 px / 20in = 25.35 px/in
rotors 348 px * 25.35 px/in = 13.72in (349mm)
So, if you believe the images, the rotors are about 0.61" larger in diameter on the 20-inch wheels.
Oddly, an illusion makes it seem like they're much larger.
I've attached my images should anyone want to do their own analysis.
Yeah, the main question is what brakes will be on the P3D without the performance upgrades package.
Will it have the standard brakes like on the LR RWD/AWD or will it have larger rotors and larger calipers (just not red)?
Or will all the P3D's have the same brakes regardless if you chose 18" or 20" wheels....
Tried calling earlier but they are too busy and said to try calling later. I did ask one of the sales reps at my local store, have to see what they say when they get back to me.The felling I have seen elsewhere bu people much more knowledgeable than I is that the caliper could just be the same one, just with a bigger rotor to improve performance. I will be excited to get an answer. Don't suppose calling one of the support numbers for sales could get us any information?
There's a strong possibility that the calipers are the same across all Model 3s, but a different red color for Performance.I called 3 different showrooms today that told me the $5,000 performance package adds different calipers that come on the standard performance model. I still don't know what to believe, but I thought I would share.
I'm also waiting to hear back from Tesla on the specifications for what comes on each model. Still waiting for official confirmation.

The larger rotors make much more of a difference than the calipers, but generally ONLY for the race track.
MPP uses the factory caliper, but a larger rotor. Sasha reported no brake fade at all with the larger rotor and factory caliper on a race lap.I completely agree that a lot of performance can be found with enlarging the rotors. I know we are all speculating here, but the pad contact area on the rotor looks larger on the P model, indicating different calipers. We'll have to wait and see.
FWIW, I really like the MPP rotor design. If the same calipers are used throughout all models, there's no question I'm un-checking the $5,000 performance package box and using MPP instead. The upgraded brakes are my only incentive to add the package, but I am one of the few owners that will actually track their M3.
Because you're replying to posts made OVER A MONTH AGO. Check the dates. Yes, we've obtained updated information since then.Guys, why is this B.S. still floating around?
I've been misled too often by well-meaning but incorrectly-informed Tesla sales staff to simply accept anything that they say without confirming it elsewhere.Tesla has confirmed this to many customers.
You need to clarify:Please stop B.S.ing that both cars have the same rotors. They do not.

The $5k Performance upgrade adds larger rotors. It was CONFIRMED by earlier versions of the owner's manual where they gave the specs for the larger rotors. It was CONFIRMED because 18" wheels DO NOT fit on the $5k Performance upgrade cars. Tesla has confirmed this to many customers. Please stop B.S.ing that both cars have the same rotors. They do not.
Agree on all of the above.Because you're replying to posts made OVER A MONTH AGO. Check the dates. Yes, we've obtained updated information since then.

You need to clarify:
For Performance with the Performance Upgrade package:
- AWD appears to use the same exact rotors and calipers as RWD.
- Performance without the upgrade package also appears to use the same exact rotors and calipers as RWD.
Reference: Model 3 Owner's Manual, page 140
- The rear rotors are the same diameter as on the other vehicles (335mm). It may still be a different rotor, but the diameter is the same.
- The rear caliper is definitely larger, and appears to be the reason why 18s won't fit.
- The front rotors are larger than on the other vehicles (355mm vs 320mm)
