What is the benefit of a two-piece rotor with an aluminum hat?

A two-piece rotor with an aluminum hat offers several advantages. The aluminum hat significantly reduces unsprung weight, which can improve vehicle handling. It also helps to dissipate heat, preventing excessive temperature transfer to the hub and potentially reducing brake fade during demanding use.

What does the 'XD' designation mean for this DBA rotor?

The 'XD' designation indicates DBA's enhanced rotor design. For the 5000 Series, this includes a non-directional cross-drilled and dimpled pattern. This design not only offers improved cooling benefits over standard finishes but also contributes to a more aggressive, sporty appearance.

Can I replace just the braking surface on this rotor?

Yes, the DBA 5000 Series is a two-piece rotor system. This means you can purchase replacement braking rings (flat discs) separately when the current ones wear out, allowing you to reuse the aluminum hat assembly and save on future replacement costs.

About this part

Product Details

The T6061-T6 aerospace-grade aluminum hat on this DBA 5000 Series rear rotor is a key feature, designed to significantly reduce unsprung weight compared to a traditional one-piece rotor. This isn't just about shaving grams; it also helps manage heat by limiting its transfer from the cast iron braking ring to the wheel hub, which is crucial for maintaining consistent braking performance, especially during spirited driving or track use.

This is a two-piece rotor assembly, meaning the high-carbon cast-iron braking ring is bolted to the aluminum hat using NAS bolts and crimp nuts. This construction allows the cast iron ring to expand and contract uniformly as it heats up and cools down, which can help prevent warping and cracking over time. The XD series features a non-directional drilled and dimpled design, which helps with cooling and provides a sportier look. These rotors are a direct replacement for your Mustang GT's rear brakes, specifically designed for vehicles equipped with the Performance Package.

DBA recommends this 5000 Series rotor for high-performance street applications, track days, club racing, and rally use. Because it's a two-piece design, you can also purchase replacement hats and flat discs (rings) separately down the line, allowing you to keep the aluminum hat assembly and just replace the wear surface when needed.
