There are several differences between the Model Y Long Range and Model Y Performance versions. So, owners of Model Y Performance can count on more dynamic acceleration and a higher maximum speed, although these indicators are rather software limited. Also, the difference is manifested in the size of the wheels and the performance of the brakes. This is already a physical difference.
The larger Brembo brakes are probably the most significant upgrade for the extra money Tesla is asking for the upgrade to the high-performance version. However, it turns out that Tesla compromised the brakes on the Model Y Performance and did it in a very sneaky and secretive (if not deceptive) way. The changes were discovered and exposed by the company ZEV Centric, which produces accessories for Tesla cars.
ZEV Centric has worked on various customer Model Y vehicles and its own vehicles, and discovered brake replacement in the process. These were cars of different years of production.
The Performance upgrade for the Model Y involves the use of a Brembo rear caliper and a thicker rotor (by 2 mm) with additional ventilation functions. The company revealed that around September, Tesla began replacing that Brembo caliper (right) with a new Mando brake (left).

In addition, as ZEV Centric assures, the rotor has become 2 mm thinner, that is, it has also undergone a downgrade.
ZEV Centric, who are brake experts, believe this is a significant degradation. The company believes that Tesla should provide them with Brembo brakes, as this change was not specified in the Tesla Model Y configurator.
It should be noted that this is not the first reduction in price that Tesla has made to reduce costs. The company has previously removed some available features and capabilities from its cars, including passenger seat lumbar support controls and ultrasonic sensors.
