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

The slots help to remove brake pad dust and gases that can build up between the rotor and pad. This allows for better contact and more consistent braking performance, especially under heavy use. The drilled holes also help with heat dissipation.

Are these rotors directional?

Yes, these are uni-directional rotors. The cross-drilled and slotted pattern is designed to be installed on a specific side of the vehicle to ensure proper function of the ventilation system.

What is the Kangaroo Paw ventilation system?

The Kangaroo Paw ventilation system is DBA's patented design that uses a series of pillars within the rotor's vanes. This design increases the surface area for heat dissipation, helping to keep the rotor cooler during braking.

About this part

Product Details

DBA is known for making solid brake components, and their 4000 Series XS rotors are a great example of that. If you're looking to replace the rear rotors on your 2004-2013 Mazda 3, especially if you have a Mazdaspeed model, these are a direct replacement that offers improved performance over stock.

These rotors are built from high-carbon, heat-treated iron, which helps them resist warping under stress. The unique drill and slot pattern on the 4000 Series XS Gold rotors isn't just for looks; the slots help clear out brake dust and gases that build up between the pad and rotor. This means you get a more consistent grip, especially during harder braking. The Kangaroo Paw ventilation system also helps keep things cool, which is crucial for maintaining braking performance.

You'll get a noticeable difference in how your brakes feel, particularly when you need them most. The gold finish on the hub is a nice touch, offering some protection against rust in that area.
