The EBC slotted rotor and Akebono caliper bracket were installed along with the EBC Yellow Stuff brake pads. All EBC rotors are British-made and are precision-machined in the UK. Rotors are made from high-quality gray iron to exacting standards and undergo extensive testing and rigorous quality control. Slotted rotors can significantly improve brake performance and longevity when used with a matching high-friction pad set such as the EBC Yellow Stuff pads. The Yellow Stuff pads are high-friction aramid fiber pads, are totally resistant to brake rotor vibration, and are gentle on rotors compared to conventional pads.
