Fitment Details
Compatible with BMW Z4 rear left, 2006-2008. Also fits BMW M3 rear left, 2005-2006, with Competition package and ventilated rear brake setup. This part number 150.3453.70 is also listed for BMW M3 rear left from 12/2004 with the same Competition package and ventilated configuration.
This part cross-references Carlson 17236 for the same application.
Why This Rotor Design Matters
Zimmermann developed the Formula Z rotor for vehicles that experience elevated brake temperatures, including tuned engines and chassis upgrades. The floating mounting allows the rotor to expand radially under load, which helps reduce stress concentration and heat-crack formation. For BMW Z4 and BMW M3 rear brake service, part number 150.3453.70 provides a direct replacement format with ABE/ECE documentation supplied with the rotor.
Common Problems This Rotor Can Address
- Brake vibration or pulsation from worn rear rotors
- Reduced braking consistency during repeated high-load stops
- Surface corrosion on exposed brake disc components
- Heat-related cracking on heavily worked rear brake rotors
- Fitment issues when replacing a two-piece rear left BMW rotor
Installation Notes
Verify rotor dimensions, hub bore, bolt pattern, and minimum thickness before installation. This rotor is specified for the rear left position only, and BMW M3 applications require the Competition package with ventilated rear brakes. Replace in axle pairs when service procedures call for matched braking surfaces, and confirm the paired article number 150.3454.70 for the opposite side.
Quality Assurance
Zimmermann supplies this Formula Z rotor with coated anti-corrosion protection and ABE/ECE certification documentation. The two-piece construction, floating hub design, and high-carbon machining are intended to meet the demands of performance-oriented BMW brake service.
