The EBC BSD rear rotor set is specified for 2006–2007 BMW 325i E90 applications and uses a V-slot pattern to aid heat dispersion and pad cooling. These vented rear rotors are built with thermally stable high-carbon material and the new vee slot design with a silent slot pattern, aiming to add improved thermal control and a performance-oriented look compared to standard OE rear rotors.
