Give your 1 Series sharper, more confident stopping with this Zimmermann Coat Z front rotor. The 150.3423.20 uses high carbon castings with a protective silver coating to fight rust, control heat and keep braking smooth and consistent in real-world driving. Ventilated channels help manage temperatures on fast A-road runs and daily commutes, while the OE-match geometry ensures a precise, hassle-free fit. We have fitted these discs in our own workshop and customer feedback on bite, modulation and refinement has been excellent.
