Zimmermann 150129052 Coat Z Cross-Drilled Brake Disc Rotor

The Zimmermann 150129052 is a high-performance cross-drilled brake disc rotor engineered to meet OEM specifications for BMW vehicles. This German-manufactured rotor features Zimmermann's advanced Coat Z anti-corrosion coating technology, which has been protecting brake rotors since 2008.

Key Features:

• Cross-drilled design for improved heat dissipation and reduced brake fade
• Coat Z anti-corrosion coating prevents rust formation at the hub for better longevity and improved appearance
• High carbon grey cast iron construction with flake graphite for exceptional durability and thermal resistance
• Can be mounted directly out of the box without removing the coating
• Manufactured in Germany in conformity with DIN EN ISO 9001:2008 and DIN ISO TS 16949 standards
• OE-quality replacement designed to match factory specifications

The cross-drilled design is race-proven to improve brake performance by effectively absorbing and redistributing friction-based heat, helping the rotor stay cooler and drier under all driving conditions. Zimmermann's proprietary material compound is precisely matched to vehicle specifications and includes supplements such as copper, molybdenum, titanium, and carbon for optimal performance and longevity.
