R1 eLINE Silver Drilled & Slotted Brake Rotor Series:

R1 eLINE Silver Series brake rotors combine cross-drilled holes and diamond slots with a silver zinc-plated finish for corrosion resistance on non-friction surfaces. The drilled and slotted pattern is designed to support heat dissipation, pad contact and debris evacuation during street and performance-oriented braking.

The rotor braking surfaces use a double-disc-ground, non-directional machined finish to support smooth pad bedding. The silver zinc coating initially covers the rotor and is designed to wear from the pad-contact surface during normal bedding while remaining on non-friction areas. Rotor construction and dimensions such as solid or vented design, diameter and thickness vary by application.
