The Baer EradiSpeed+1, 2-piece rotor upgrade features a premium, larger diameter than stock, purpose-cast rotor mounted to a black anodized, 6061-T6 aluminum hat with NAS aircraft grade hardware. EradiSpeed+1 rotors are manufactured from high-quality iron with increased mass in the friction area. Their curved-vane design promotes greater airflow and improved heat dissipation, helping them outperform the factory rotors they replace. A slotted and drilled friction surface provides an escape path for dust and gases produced during braking, resulting in a more consistent pedal feel and braking performance. The rotors are also zinc-plated to help resist rust and corrosion. The EradiSpeed+1 is a direct-bolt-on system designed for simple installation, with no brake bleeding required. NOTE: Slot-only versions are available (and recommended) for Autocross, Track-Day, Etc. conditions. Please contact Baer directly to place your order.
