08-12 BMW 135i Performance Brake Rotors Noise Reduction Technology Front For Sale - New and Used

Made From Centric Premium High Carbon Rotors

Centric premium high carbon brake rotors contain an advanced metallurgy that greatly reduces the possibility of pad squeal especially with higher friction, European style brake pad compounds. Proprietary Molybdenum and Chromium alloys resist rotor cracking during high performance use or repeat stop situations. This alloy also increases the friction couple improving brake performance and stopping power. Increased Chromium and Carbon content is also more resistant to oxidation.Feature Original Equipment specifications and manufacturing process to meet QS and ISO Quality System Standards.

Centric premium rotors utilize an Electrocoating finish that provides long lasting corrosion protection. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. Phosphate finishes utilized by other manufacturers provide only minimal protection from the elements; these finishes are generally only effective for the shipping and storage portion of a rotor’s life. The addition of heat and moisture eliminates the effectiveness of phosphate finishes resulting in immediate corrosion once installed in the vehicle.

Centric brake rotors feature a double disc ground finish which virtually eliminates run out and any disc thickness variation issues. Double disc grinding also produces a non-directional finish for improved rotor and pad break-in.

Exclusive black E-Coating on all non-friction surfaces. E-Coating is an advanced electro-statically applied finish that has been engineered to withstand 400 hours of salt spray testing without corroding.

Centric rotors utilize the same split core symmetric molding process used by OE manufacturers. Rotors with symmetric core molding dissipate heat more efficiently to both sides and provide better stopping power especially in repeat stop situations.

Some of our competitor\'s rotors

Don\'t be fooled by the low quality zinc plated rotors. These rotors has very low quality the metallurgy 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. Zinc plating does not improve the quality of the rotor. Quality rotor has to start with high quality metallurgy and craftsmanship.

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.

We also offer the following patterns below

Cross Drilled:

Recommended for everyday driving for driver who want to improve their brake but without the aggressive bite of the slot. It\'s pad friendly will not wear out the pads. It will increase cooling to prevent premature warping and brake fade.

Cross Drilled/Slotted:

Recommended for aggressive driver who want cooling of the cross drilled with an extra bite. The slot will increase initial pad bite when brake pedal is applied. The slots also help keep the pads surfaces clean and free of glazing as well as heat dissipation.

Slotted:

Recommended for aggressive driver, sport driving, and towing application. The slot will increase pad initial bite when brake pedal is applied. It will also help keep the pads surfaces clean and free of glazing as well as heat dissipation. Since it is not cross drilled there is no sacrifices in the structural integrity of the rotor.

Dimpled/Slotted:

Recommend for aggressive driver who want cross drilled and slotted look without sacrificing the structural integrity of the rotor. Excellent for all driving style, sport driving, towing, as well as everyday commuting. The slot will increase initial pad bite when the pedal is applied. The dimple gives it the cross drilled look and help dissipate heat from the surface of the rotor.

Warranty:

3 years warranty against cracking, 1 year against warping. Warranty will not cover improper installation or missed handling or competition driving. Customer is responsible for returning item(s) to DRT for warranty. All warranty will be inspected and to be determine by DRT. Customer is responsible for all shipping cost to and from.

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.
