RacingBrake.com Stock Rotor Replacement
This stock rotor direct replacement offers you the best value for immediate improvement of your brake performance at a price often lower than you would pay to a car dealer for an OE replacement.

Our rotors are not just made to fit, like aftermarket replacements, nor like some of our competition that buy ‘off the shelf’ stock rotors and drill or slot merely to meet the “performance” look.

We make real performance rotors from the ground up. First comes design. A CMM is used for precise measurement, then 3D computer modeling is used for design with improvements to make up the shortfalls of OE design and for performance enhancement. The following examples are proof of our superiority to OE or competition.


RacingBrake.com Design
Reinforced Rib
This patented design is added to improve the strength of Subaru’s WRX rotor based on our exclusive design criteria of “Torque Ratio”. In addition, the ribs also increase air circulation. The result is that our rotors don’t have the same problem of warping as OE rotors. Subaru enthusiasts love our rotors because our better design results in a stronger and cooler rotor.

Similar reinforced ribs are added to other rotors with the same criteria for other applications.
 

Curved Vane
Some of our ventilated rotors are selectively upgraded from OE straight vanes to curved vanes as we deem necessary for performance, as most people are aware that curved Vanes pump more air and keep discs cooler than straight vanes. However, curved vane discs are “directional,” meaning that the left and right discs are different and require two sets of tooling at the factory. Straight vane rotors can be made from the same single set of tooling.

We spend more time and money in extra tooling. Our products are based on performance needs, not just cost. We invite you to check around in the performance market and see if any manufacturer offers the same upgrades as RacingBrake.  Click here to see details of application list

RacingBrake.com Production
Material
Our rotors are made of material upgraded from the OE standard of SAE J431 Class G3000 (30,000 psi in tensile strength, 187-241 in Brinell hardness). More important is our know-how and experience over decades in cast iron metallurgy. All rotors may appear the same but under a microscope there is a world of difference in metallurgical structure, which per ASTM A-247 the type (shape) of graphite shall be VII or flake graphite with “A” type uniform distribution and random orientation, and graphite size.

These are published data but achieving the optimal casting requires years of metallurgical experience and precise control during the casting process. Carbon (graphite) contents and structure greatly dictate the mechanical property of the cast iron for a brake rotor. Brake rotors are subject to sudden and extreme heat load cycles while a is braking. Proper material and casting can help a rotor perform optimally and be more resistant to wear, without warping or cracking.

Heat Treatment
Severe brake duty cycles require not only good material but need proper heat-treatment to relieve the residual stress and further enhance the microstructure uniformity. Over the years, we have developed a proprietary process in temperature and time control to achieve the optimal result.

RacingBrake.com Machining
All of our rotors are machined by advanced CNC to a general tolerance of ±.004” and ± .002” for critical dimensions such as parallelism, thickness variation and indicator runout. We claim our tolerance in figures rather than phrases such as “tightest in the industry,” like the competition does. These tight tolerances are our best assurance of fitment, easy break-in and demanding brake performance without pulsation or vibration.

RacingBrake.com Finish Coat
Rotors are subject to rust, and most rotors are not protected against corrosion in early years. It is not uncommon to see a rusty rotor on a car dealer’s brand new show car. When we started our performance line about four years ago, we tried and experimented with various surface coatings, and found EDP (Electro-Deposition Paint) gives the optimal result in durability and cost.

Not only does EDP provide lasting protection against corrosion (lasting about 500 hours in a salt spray test, vs. 100 hours for common bright zinc plating), it has an appealing black look. In addition, it is environmentally friendly, unlike the cadmium or gold zinc plating (which uses hexavalent chromium) used by the competition.

Both cadmium and hexavalent chromium heavy metals are classified as hazardous substances and are prohibited from being used by the EPA (see more discussion at http://www.finishing.com/60/49.shtml). RacingBrake was the first company introduced EDP to the performance industry. You may see some imitators achieve the same black look with a fancy name but they are not the same as ours.

RacingBrake.com Packaging
Our rotors are protected with anti-rust oil for the friction surface where the paint was removed by double cross grinding. Rotors are packed in pairs in a strong and appealing RB logo box, not in a generic white box. Our quality stands inside and out.

RacingBrake.com Identification
We stand 100% behind what we make. All RB rotors are cast or imprinted with: TPM (company name), 9004 (Our P/N), MIN THK 22.0 MM, Lot# for identification. Our rotors also have an engraved direction arrow, where applicable, to assure error proof installation (Even slotted straight vane rotors are directional). These marks are not just for identification. They are your assurance and our symbol of quality racing components.

RacingBrake.com Conclusion
These are just highlights of how our rotors excel, from OE replacement to high performance brake rotors. RB clearly leads the way by offering the finest quality performance rotors in the marketplace.
