Improved fatigue resistance to minimize surface cracking

Reduced rotor fatigue during prolonged heavy braking

Quick replacement, minimal “bedding-in” of rotors

Style: Slotted

Finish: Silver

Note: Special Order. Ships usually in2-3 weeks.

Description

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 Tesla Model S. 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.

TSP is a proprietary process specifically developed by DBA for improving the performance of disc brake rotors. For more on this, check out the “Features” tab on this page.

Benefits

• Improved fatigue resistance to minimize surface cracking
• Reduced rotor fatigue during prolonged heavy braking
• Quick replacement, minimal “bedding-in” of rotors

Features

Thermo-Graphic markings

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.

Kangaroo Paw Design

“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.

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.

Longlife Slotted Design

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.

Inside the Technology

Highlights

• 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

Who is DBA?

With more than 40 years of industry experience and know-how, DBA Rotors has become Australias most awarded manufacturer and a global leader in brake rotor development. Over the years, DBA has managed to consistently refine and deliver quality braking solutions for a wide range of vehicle applications. The company, with its thirst for innovation, is dedicated to continuous R&D and improvements in engineering.

DBA Rotors was founded in the 1970s, producing a single type of disc on a standard workshop lathe. Since its inception, the brand has proudly grown from a small local Australian manufacturer to a global supplier of disc rotors and pads. DBA distributes its products across Europe, Australia, The Middle East, Russia, Asia, the U.S., and everywhere in between. Its comprehensive lineup of direct replacement disc rotors and pads cater to street vehicles, 4x4s, SUVs, military and armored vehicles, track cars, and more! Its application range includes everything from performance upgrades to towing, off-roading, and motorsports. DBA rotors come in several different series and offer just the bite you want in your braking system.

Why Choose DBA Rotors?

DBAs number one priority is safety and takes no short cuts when it comes to manufacturing disc brakes. Drivers all around the world trust DBA products for their consistency, reliability, and superior performance. In fact, DBA performance rotors have been used and proven successful on many race tracks around the world and in several motorsport categories. DBA is world-renowned for engineering discs that are far better to the generic and aftermarket counterparts. It sets the bar when it comes to quality, tolerances, premium materials, and manufacturing equipment that all come together to deliver the finest disc brake rotors on the market.

In addition to standard direct replacement rotors, DBA manufactures a wide range of enhanced performance products. These boast features such as slotting, cross drilling, top-grade materials, improved appearance, and, in the top-line series, a highly sophisticated two-piece design. DBA rotors also spotlight a patented Kangaroo Paw ventilation system that helps your braking system remain cool and strong. DBAs Thermo Stability Profiling is optimized to improve the longevity of your brake pads. Thermo-Graphic heat paint on each DBA rotor changes color based on different temperature limits, so you can monitor your brake system with a quick glance.
