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.
