Important Note:

Brakes are a safety critical part of a motor vehicle. Brake components should be installed by a competent mechanic in a professional manner. Any incorrect installation of brake components can cause a major safety problem or an accident. If you are not a competent and qualified mechanic you should not attempt to install these products, but should take the vehicle to a vehicle dealer or competent automotive mechanic for their installation.


Disc brake pads and rotors are wear items and as such, should be inspected regularly and replaced as necessary. Read More.

The DBA 4000 Series T3 Rotor has a Tri-Symmetrical design for extreme stopping power on the road and the track and complement the looks of any performance car. As with every DBA rotor, the 4000 Series T3 Rotor bolts right onto the vehicle with no mechanical changes needed.

DBA's mid-series, enhanced-performance, slotted rotor features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring.

Thermal Stability Profiling

TSP is a proprietary process specifically developed by DBA for improving the performance of disc brake rotors.

Benefits

  • Improved fatigue resistance to minimize surface cracking
  • Reduced rotor fatigue during prolonged heavy braking
  • Quick replacement, minimal "bedding-in" of rotors
Thermo-Graphic Temperature Monitoring

Thermo-Graphic markings are placed on the outer edge of each DBA 4000 series disc rotors and are used to monitor the core temperatures achieved during braking application. The markings change color as the rotor heats up to alert the driver to rotor temperatures that exceed optimum levels.

Initial ColorWhen rotor exceeds this temperature...The color will change to...
458°C
550°C
630°C
Kangaroo Paw

"Kangaroo Paw" is a patented, high-tech disc rotor ventilation system designed and manufactured in Australia by Disc Brakes Australia and available on rotors for select applications. "Kangaroo Paw" technology delivers significantly improved braking performance. Even under extreme braking conditions. Kangaroo Paw rotor designs run cooler, are stronger, and outperform traditional straight-vane disc rotors.

Kangaroo Paw Rotor

The "Kangaroo Paw" design features a series of 144 diamond- and tear drop-shaped pillars and columns individually spaced between the rotor faces.

This system provides two key advantages.

First, is the ability to cool the rotor faster than ever before. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot air out from within the internal areas of the rotor.

Second is increased dimensional stability across the disc rotor directly achieved by the individually spaced pillars and columns.

These advantages increase the disc rotor's efficiency by as much as 20% when compared to conventional rotor designs. A 20% increase in disc rotor efficiency directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder.

All 4000 series rotors also benefit from DBA's "Longlife Slotted" design. The rotors are manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix resulting in long wear and safe, consistent stopping power.

  • Unidirectional slotting (left and right) increases pad bite, reduces fade and delivers exceptional braking performance.
  • Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring.
  • Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
  • Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt.
  • Slotting also combats "out-gassing," where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power.

DBA rotors are chosen as Original Equipment on many vehicles.

    3.6 out of 5

    The brake rotor and pad combination that I currently use is primarily for track days. For them to function well on the street daily driving you either have to react earlier, or drive very aggressively. The rotors have been excellent, do not warp, provide an incredible surface for the pads to work on, but with aggressive performance pads the rotors wear very quickly in comparison to other set ups (I am on my second set of rotors in 2.5 years). HP Plus enhanced performance pads provide outstanding feel, fade resistance and very high stopping power. Outside of track use they are very squeaky (noisy). Even when not up to operating temperature they have a very high grip coefficient and require a soft touch during street operation. They are also very dirty. Cleaning wheels becomes a daily maintenance item when using this combination. The brake lines allow for maintenance of excellent brake pedal feel.

    I have used these with hawk performance plus brakes and have been great. Look amazing and get lots of compliments. But driving wise, I have used on highway, long trip at high speeds, autocross and on a spirited tough road...so I have gotten them VERY hot and so far been excellent. No fading or warping and perform great. I despise the hawk pads, so DO NOT recommend those, but rotors are great!

    4.7 out of 5

    I am very pleased with the combination I installed. Always wanted to try DBA rotors and Tire Rack had them on special. The new Redstuff pads took a bit to bed in, but once they did, I am thoroughly impressed! This combination has led me to leave a review for a product, which I have never done before. These rotors are very high quality and respond awesome. I will definitely be buying DBA rotors again in the future for my other cars. The only gripe I have about the DBA rotors is the anti-rust finish comes off fairly easily, especially when brake cleaner is used on them right out of the box. Do not spray the cleaner on, spray on a rag first and then wipe the surface off, being careful not to contact the coating.
