The OWNSILENT & Co Carbon-Ceramic Brake Rotors for the Polestar 4 are precision-designed to fit the OEM front and rear rotors used on this compact all-electric SUV, supporting both single-motor and dual-motor powertrain options. Though official rotor diameters aren’t broadly published yet, these rotors are built to exact OEM specifications for perfect integration with factory brake systems on 20″, 21″, and performance pack configurations. The carbon-ceramic material offers superior thermal stability and fade resistance with reduced unsprung mass and brake dust compared to steel rotors.
