Noise Reduction Technology(NRT)
One of the reason why Mercedes are so smooth and quiet is that theirvehicleshas anti humming rotors (harmonic balancing) rotors from the factory. 99% of the companies that sell cross drilled rotors does not have harmonic balancingtechnology it will create unwanted noise inside the cabin during braking
DRT Noise Reduction Technology (NRT) will eliminate the humming noise during braking. Conventional cross drilled/slotted rotor create harmonic frequencies (humming) during braking. Noise Reduction Technology (NRT) the drilled/slotted patterns are machined 180 degrees from each other. When the brake pedal is applied, one side will create positive harmonic frequencies, and the opposite side will create negative harmonic frequencies. The positive and negative frequencies will cancel each other out to reduce the humming noise. The left wheel and right wheel will also cancel out each other. NRT rotors will eliminate humming noise in the cabin for a comfortable driving experience.
NRT rotors does not have any negative affect on the performance nor will it reduces the longevity of the rotor. It has been tested and proven to reduces humming noise.
Knife Edge Slot
DRT Sport rotors feature a knife edge slot design. The end of the slots are machined at an angle to create a ramp which helps channel out the brake dust. With every rotation the slots keep the brake pad surface clean of brake dust and prevent glazing. Brake performance will also increase with more positive pedal feel. Cross drilled holes are designed to increase air circulation for maximum cooling. During wet driving condition the slots and drilled holes will channel out water from the friction surfaces.

Drilled/Slotted By DRT In U.S.A From 100% Genuine Brembo Rotor
Why do we use Brembo as a raw material? Simply it\'s the best brake rotor available on the market. Over 50 years experience in the brake business. Over 80% of the world\'s motorsports racing uses Brembo brake. Formula 1, Indy car, Nascar, World Rally, MotoGP, WSBK.
Quality product starts with quality material and craftsmanship

Some of our competitor\'s rotors
Don\'t be fooled by the low quality zinc plated rotors that will cost you more for the long run. These rotors has very low quality the metallurgy and workmanship it will not meet the manufacturer\'s specification of your vehicle. The internal vane structure are tapered style which doesn\'t meet OEM specification. Tapered vane does not distribute heat evenly to both sides of the rotor which will lead to a premature warping. Zinc plating are not intended to be use on brake rotor. When brake dust is exposed to the road\'s elements and moisture it will form hydrochloric acid, which will deteriorate the plating very quickly. Once it\'s deteriorated the rotors will rust in a couple of months. Zinc plating can be use on interior components which are not expose to the road\'s elements, just not on brake rotors. Quality rotor has to start with high quality metallurgy and craftsmanship. Zinc plating low quality rotordoes not improve the quality of the rotor.
There are only a few companies that manufacture high quality rotors that will meet or exceed OEM specification. Unlike other sellers DRT discloses all information about the blank rotors or raw materials.You will get what you pay for.

To avoid costly mistake we highly recommend that you hand torque the wheels to the manufacture\'s specification every time it is removed. Allow the brakes to cool down before washing the vehicle. Washing the vehicle while the brakes are hot will distort the rotors. Wheels that are larger than the factory will put more stress on the brakes and it will lead to premature warping. Towing or carrying extra weight will also reduces the life of the rotors and pads.
