DBA 16-20 Lexus GS F Front 5000 Series Cross Drilled Rotor w/Silver Hat

DBA is well-known for making robust braking components that stand up to demanding use. This 5000 Series rotor is a prime example, designed as a direct replacement for your 2015-2019 Lexus RC F. It's a two-piece rotor, meaning the high-carbon cast-iron braking ring is separate from the T6061-T6 aerospace-grade aluminum hat. This design is key to its performance, as it allows the iron ring to expand and contract uniformly with heat, while the aluminum hat helps manage heat transfer away from the hub.

The XD finish on this rotor features a non-directional cross-drilled and dimpled pattern. This isn't just for looks; the drilling and dimpling help with cooling and structural support, especially under strenuous driving conditions like track days or spirited street driving. By using aerospace-grade aluminum for the hat, DBA significantly reduces the unsprung weight of the rotor assembly, which can lead to improved handling. These rotors are held together with National Aerospace Standards (NAS) bolts and crimp nuts, ensuring a solid connection between the hat and the rotor ring.

Because this is a two-piece assembly, you have the flexibility to replace just the rotor ring or the hat down the line if needed, allowing you to reuse the DBA 5000 Series hat with replacement rings. This makes it a solid option for high-performance street vehicles, track day cars, club racing, and rally applications where consistent braking performance is crucial.
