Hello Tesla Community, I am new and I would like to know if anyone has upgraded the rear brake calipers/rotors for the performance. I also heard that some rear calipers from the model S fit the Model 3 SR I have currently have 20-inch wheels. Please let me know. Curious to see the options and Thank you.

Have you tracked it yet? I see you have 20” wheels - not really ideal for track purposes. You’d be better off with the 18” wheels and stickier tires.

Have you tried changing pads first? Also recommend changing to high temp brake fluid.
Hello, yes you are right i use the 18" michelin primacy then change it to my 20" it seems like standard brakes overheat so i am thinking on swapping the rotors along with break pads and calipers. Although there arent many options and it seems like using the ones from the performance model might give you some codes. I am still doing my research.

You can get a full set of Performance rotors and calipers, plus the factory parking brake wiring harness for each caliper. This way you'll be able to upgrade to the Performance rear brakes and the car will be happy.
