DBA® 42723S - 4X4 Survival™ T3 Slotted 1-Piece Rear Brake Rotor

Benefits:

• Ensure increased pad bite and improved air circulation
• Clean and de-glaze pad surface for optimum pad coefficient of friction
• Create an escape route for debris, dust, and water
• Reduce stopping distances in wet weather
• Offer much faster heat dissipation
• Resistant to warping and fading

Slotted rotors by DBA are a great alternative to drilled rotors. They serve the same purpose of breaking down hot brake gas but provide better resistance to cracking. The slotted pattern allows for increased pad bite and improved air circulation. The slots help to sweep away gas and dust. If you drive hard, race or use your vehicle off-road or for towing purposes, slotted rotors are a perfect choice for you. The internal vane design of these vented rotors by DBA provides excellent heat dissipation during brake cycles. As the wheel spins, the vanes around the edge of the rotor draw air in and pull it through to help cool the rotor. With the extra heat dissipated there will be less brake fade.

T3 4000 series rotors are DBA's highest performing 1-piece rotors that deliver fade-free performance on the racetrack, effective grip during street racing and drifting, and comfortable, easy-to-use operation under normal driving conditions. These rotors are also best suited to high-horsepower passenger cars one might find travelling German autobahns at triple-digit velocities. Each T3 4000 series rotor features 48 grooved slots on the rotor surface to wipe away and remove any excessive heat, dust, and gasses that build up during extended braking at high speeds. You will also find those performance benefits continue in the rain, and pads will wear more consistently and eliminate "lip" formation along the outside edge of the rotor. If you're installing T3 4000 rotors with new pads, the rotors will most likely be usable with a second set of pads when the first wear out. Protective paint is applied on all non-contact areas to ensure these rotors continue to look good and resist corrosion during their extended lifespans.

For the serious performance driver that's mindful of avoiding high rotor temperatures that cause brake fluid boiling and pedal fade, DBA equips each T3 4000 rotor with three paint marks that monitor brake rotor temperature and change color as different points are reached. A green line becomes white at 856 degrees Fahrenheit, an orange line changes to yellow at 1,022 degrees Fahrenheit, and a pink line also changes to white when temperatures exceed 1,166 degrees Fahrenheit. While these brake rotors will reach high temperatures eventually after heavy sustained use, they will take longer than others to reach those temperatures. They'll maintain their cool under most conditions thanks to high-carbon iron construction which resists temperature buildup better initially, and because of vented centers with 144 tear-drop shaped pillars which result in more metal contact and better cooling than traditional fins.

Like all high-performance DBA rotors, T3 4000s are cured during production and heat-treated with a patented Thermal Stability Process - reducing metal stress and preventing iron from weakening internally over many heating and cooling cycles. Combined with lower overall operating temperatures, these rotors are much more resistant to the warping and hotspotting which typically shorten both pad and rotor lifespan. DBA matches or exceeds vehicle manufacturer rotor warranties by ensuring that these brake discs will remain usable and free from defects in materials and workmanship for a period of 1 year or 12,000 miles.
