Is this a complete brake rotor or just the friction ring?

This is a replacement friction ring only. It is designed to be bolted onto an existing DBA 5000 Series aluminum brake rotor hat. You will reuse your current hat if it is still in good condition.

What is the benefit of the aluminum hat on this rotor?

The T6061-T6 aluminum hat significantly reduces unsprung weight compared to a full iron rotor. It also helps manage heat by allowing the cast iron ring to expand uniformly and reducing heat transfer to the hub.

What is the difference between the HD variant and other 5000 Series rotors?

The HD (Heavy Duty) variant features a smooth, OE-style friction surface. This is preferred by some drivers for its quiet operation and appearance, while still offering the performance benefits of the 5000 Series design.

Product Details

If you're looking to get your 2015-2021 Nissan GT-R Nismo back on the road with top-tier braking performance, this DBA 5000 Series replacement rotor ring is what you need for the front left side. This is a direct replacement for your factory two-piece rotor assembly, specifically designed to work with the existing aluminum hat. DBA is known for making solid brake components, and this rotor ring is built to handle demanding driving conditions, whether it's spirited street driving or track days.

What sets the 5000 Series apart is its construction. It uses a high-carbon cast-iron friction ring bolted to an aerospace-grade T6061-T6 aluminum hat using NAS bolts. This two-piece design offers several advantages. The aluminum hat significantly reduces unsprung weight compared to a full iron rotor, which can improve handling. It also helps manage heat, allowing the cast iron ring to expand uniformly without transferring as much heat to the hub. This specific model is the HD variant, meaning it has a smooth, OE-style friction surface, which is a popular choice for drivers who want the performance benefits of the 5000 Series without the noise or appearance of drilled or slotted rotors.

This is a replacement ring only, meaning it's designed to be bolted onto your existing DBA 5000 Series aluminum hat. This is a great way to save money if your hat is still in good condition and you just need to replace the worn friction surface. Make sure you're ordering the correct side; this is for the front left position.
