I've researched extensively on this.
Oe Brembo are Mitsubishi Evo 8 front caliper and CTS-v rear calipers
you can buy aftermarket pads for these calipers and upgrade lightly.
Or or you can get big brake kits from Brembo. They have a 6/4 piston set up for front and rear. Around $9000 USD from tire rack.
or I'd recommend getting this brake kit.

Racing nbrake has good reputation in the track world. Great deal for front and rear set up.

also have a ceramic option. This is pricy now and don't think it is worth it as ceramic is used for repeated abusive use and I doubt you'd take the tesla on track days right?
Take me a look at my tesla. I went with AP Racing Radical big brake out upgrade but you need a machinist to make you a custom adapter. 6 piston 390mm disc on my set up.
