DBA 4000 Series Slotted Rear Brake Rotor - 2018 Mazda MX-5 Brembo

The DBA 4000 Series Slotted Rear Brake Rotor provides a replacement braking surface for 2018 Mazda MX-5 Brembo.

DBA’s 4000 Series uses high-carbon alloyed iron and Thermal Stability Profiling. This combination is intended to support rotor stability through the repeated heating and cooling associated with demanding braking.

The friction surface and pad compound should be selected together. A rotor upgrade should complement the vehicle’s brake configuration and intended duty rather than substitute for appropriate pads, fluid or cooling.

The slots create exit paths for friction dust and gases at the pad contact surface. The T3 pattern uses multiple slot paths across the friction face.
