What is the main benefit of the drilled and slotted design on these rotors?

The cross-drilled and slotted pattern helps to vent brake dust and heat away from the rotor surface. This can lead to more consistent braking performance, especially under heavy use, and helps prevent brake fade.

Does this product include both rear rotors?

Yes, this listing is for a pair of DBA 4000 Series XS rear brake rotors, providing a direct replacement for both sides of your vehicle's rear axle.

What is the black hat finish on the rotor hub?

The black hat finish is a coating applied to the central hub area of the rotor. It helps to protect this part from rust and corrosion, and also gives a cleaner, more finished look behind the wheel.

About this part

Product Details

You're getting a pair of DBA 4000 Series XS rear brake rotors, designed specifically for your 2009-2018 Nissan 370Z Sport or compatible Infiniti G37 Sport models. These aren't just standard replacements; they're built with high-carbon, heat-treated iron for better thermal stability and a stronger bite when you need it most.

The unique Kangaroo Paw ventilation system works with the uni-directional cross-drilled and slotted pattern to help clear out brake dust and gases. This means more consistent stopping power, especially during spirited driving or when you're pushing your car a bit harder. The black hat finish adds a nice touch, protecting the hub area from corrosion and giving your setup a cleaner look behind the wheels.

These rotors are a direct replacement, so installation should be straightforward, fitting right onto your existing brake system. They're a solid option if you're looking to improve your braking performance beyond stock without needing to change out other components.
