Do the Performance brakes look any different?

    I'm sure you've all seen the pic of the "AWD Performance" Model 3 coming off the new line.

    Elon Musk on Twitter

    Has anyone taken a detailed look at the brakes on that car?

    Wondering if they look any different from the LR RWD brakes that have been shipping so far.

    Apart from the red brake calipers, LOL.

    They look bigger to me. I'm surprised no one has tried to match up the angle with an LR and shown them side by side. Keep in mind that those are 20" wheels.

    Calipers look bigger and the discs look bigger to me. Thought that went without saying tho, as they are ‘performance brakes’.

    I don't think that the brakes are any bigger on the performance Model S&X, they just get red calipers...

    I believe that is because the S/X ("generation 2") cars use a particular type of motor which heats up too much when you use it on the track. Therefore, no-one uses them for any significant track work. Therefore... no need for fancy brake options.

    However the Generation 3 platform uses a different motor design that allows for it to be used on the racetrack without heating up too much. So people are going to track it, and the "civilian grade" LR RWD brakes aren't up to that.

    As the 18" Aeros are an option on the P, the brakes can't be materially bigger (unless they use different brakes if you opt for the 20" wheels).

    There could be a track-capable brake option... and the car pictured didn't have it.

    Others have said that the front brakes on the LR would fit 17" wheels (it's the rear parking brake that's the problem).

    Not saying you are wrong, but are you sure there’s no space for bigger brakes on the when the Aeros are on? The standard brakes look pretty small on 20s.

    I knew the rear brakes would not fit with 17” wheels but apparently that is just the parking brake. I wasn’t trying to imply that they wouldn’t have different brakes on the P, I was just trying to make the point that Tesla is not designing brakes to take full advantage of the 20” wheels as they are also offering the Aero wheels with the P.

    Looks to me like possibly ~355mm rotors up front as compared to the standard 320mm on the LR models. These should still fit inside the barrel of the 18" aero wheel. The rear rotors most likely remain the same 335mm. Although the rears aren't "just parking brakes"...

    It's hard to tell how much larger they are, but the rotor hats sure look different.

    I don't think anyone said that the rear brakes where just parking brakes, what they said is that the parking brake portion is what would prevent using 17" wheels.

    With 20" Wheels, the extra room might be making it look bigger proportionally?

    This is by no means perfect, as the angles are different, with my car being shot at a higher angle, but it does show quite clearly that the discs (and calipers) are larger on the P.

    You’d think Elon would be open about this info. Would help make up more minds of anyone debating dual vs performance. Like me. Shrugs.

    I don't really think these pictures make that point sufficiently.

    Yeah, I'm not a huge fan of the lack of transparency either, despite ordering a P3 anyway.

    I’m waiting to configure as well. But I could definitely change my mind. It’s all in Elon’s hands right now.
