Brembo SPORT Rotors for the BMW 5-series (e34 and e39)

Brembo SPORT brake rotors are designed to fit under the factory wheels and tires utilizing the original calipers to provide improved performance and appearance.

Brembo SPORT rotors offer excellent stopping power in everyday traffic and performance driving. The SPORT system reduces operating temperatures and fade while improving wet weather performance and initial pad "bite". You can select either cross-drilled or slotted styles. Brembo brake systems are fully compatible with ABS and traction control systems. All of the necessary hardware is included to ensure seamless installation.

Brembo is the only company to win over 150 world championships and exceed the stringent performance and durability demands of the world's leading automotive manufacturers like BMW, Porsche and Ferrari. In fact, brembo is the industry leader and offers a wide range of vehicle specific brake upgrades that are designed for Optimum Brake Balance.

At the same time, Brembo manufactures brake systems for top teams in Formula 1, NASCAR, World Rally Championship and American Le mans. Over the years, Brembo equipped race cars have won more than 150 world championships and thousands of first place finishes. Brembo is the only brake manufacturer to exceed the demands of the world's top automotive manufacturers and the world's fastest race teams.

Frequently Asked Questions:

Is the biggest brake disc the best answer for my vehicle?
Not necessarily. There are many factors to take into account when choosing a performance brake system. First and foremost, a brake system must be designed based on the vehicle parameters, and the type of use it will experience. Brake systems are designed to operate best within a prescribed temperature range. While modern high performance friction materials broaden this temperature range from relatively cold pad temperatures to the high temperatures experienced in performance driving situations, the use of a disc that is too large will limit disc temperatures to the extreme lower end of this range. Not only will the disc temperature not reach the optimum range, but it will also be heavier than necessary. Below you will find an explanation of how reducing the weight of the braking system further enhances performance.

What are the advantages of drilled and slotted discs?
Drilling or slotting discs aids the disc in several ways: The edges of the slots or holes continuously clean and refresh the pad surface as well as providing increased brake "bite". Additionally, they prevent gasses from collecting between the pad and disc interface. The disc is lightened, thereby decreasing its rotational inertia. Improved ventilation increases the disc's ability to shed heat, resulting in cooler operating temperatures.

Are discs with cast-in-place holes better than cross-drilled discs?
Brembo has extensively studied and tested cross-drilling versus casting the holes in place and found no significant effect on performance or durability.

Why are there so many holes in a cross-drilled disc?
The number of holes in a cross-drilled disc is part of the engineered system. Brembo has done extensive testing with regards to the number of holes, their size, their location and their chamfering. This attention to detail is what truly sets Brembo apart in the world of braking. The same attention to detail that is delivered to the Ferrari Formula One effort is a component of the high performance program. The number of holes in a disc is in part a function of the size of the disc and the internal venting (if it is a vented disc).
