DBA 05-17 Subaru WRX STI Front 5000 Series Replacement Ring

This product is a replacement brake rotor ring for the front of your 2005-2014 Subaru Impreza. It's part of DBA's 5000 Series, which are two-piece direct replacement rotors. This means you get the high-performance benefits of a composite rotor without needing to modify your existing setup.

The 5000 Series combines a high-carbon cast-iron rotor ring with an aerospace-grade T6061-T6 aluminum hat. These components are held together with NAS bolts and crimp nuts. The aluminum hat helps reduce unsprung weight, which can improve handling, and it also allows the iron ring to expand evenly as it heats up. This design also helps reduce heat transfer from the rotor to the wheel hub. This specific variant, the HD version, features a smooth OE-style finish, making it a popular choice for drivers who want the performance advantages of the 5000 Series without the look of slotted or drilled rotors.

This is a replacement ring only, allowing you to reuse your existing DBA 5000 Series aluminum hats if you've previously installed a full assembly. DBA recommends this series for high-performance street use, track days, club racing, and rally applications.
