The DFC rear GeoSPEC coated rotor for 2013 BMW 135IS is a dimpled and slotted replacement that arrives ready to install without additional pre-degreasing. Precision cut and mill-balanced, it’s manufactured from premium G3000/G11H18 iron castings and provides superior corrosion protection compared with conventional painting. The rotor meets OEM form, fit, and function expectations and promotes faster break-in.
