The E60 and E63/4 are renowned for their sure-footed handling and its exceptional build quality. But brake rotors on bigger cars can also become easily worn due to the weight of the vehicle. To ensure the braking performance of your BMW is upheld, we recommend replacement with Zimmermann discs. As an original equipment supplier to BMW, Zimmermann's discs are manufactured to the highest standards and come with their own Z-Coat to prevent the common problem of surface rust. Made in Germany.
