Features & Product Details

RallySport Direct is proud to supply you with premium braking components brought to you by DBA, which manufactures high-quality brake rotors and braking components for high-performance vehicles, off-road trucks, as well as direct replacement rotors for passenger vehicles. Whether if it's for the street, track, or full race, DBA has a component that will suit your driving style.

On this page, you are looking at the DBA 4000 Series Drilled/Slotted Rotor. This particular rotor has been designed with several key features which include the likes of T3 Slot 48 precision CNC machined slots. These are tri-symmetrical curve slots that will dampen the vibration which makes for a quieter, more responsive and smoother brake pedal feel. This rotor also has been designed with the Kangaroo Paw 144 diamond teardrop pillar ventilation system which increases the surface area resulting in greater heat dissipation which will minimize brake fade and increases braking performance. The materials used to develop this rotor are XG150 High Carbon Alloyed Iron which allows for a greater thermal capacity which allows the rotor to handle constant extremes of heat over extended periods of time which will minimize the risk of warping or cracking.

The 4000 Series also comes with Thermographic Temperature Monitoring. These are heat paint markings that will change color at a specific temperature threshold which gives the driver an idea of peak braking temperatures, which allows for optimal choice in brake pad compound. 

Finally, the 4000 Series will also have paint protection on non-friction areas which will help reduce corrosion, and it stops any unsightly rust formation.

This is a single rotor for the rear location. 

Note: WRX guys upgrading to the STI Brembo Brakes will want to use these rotors because of their dual bolt pattern.

DBA 4000 Series Drilled/Slotted Rotor Single Rear ( Part Number: 42656XS-10)
Awesome replacement 4 years ago
5out of 5stars

I just put these on the front and back and there is absolutely no heating up during daily driving which is nice. I also used hawk ceramic pads which if I could do it over again, I would go with either stock pads or ferodo pads. They look great and the price wasn't 1/3 as bad as taking my car in to get the brakes done @ Subaru. Thanks for the great advice Zach from RSD!
