• eLINE Black Series drilled and slotted rotors: high-quality stopping power at an affordable cost.
• High Performance Brake Rotors: G3000 grade cast iron with zinc finish for ultimate rust protection. Built to O.E.M. specifications, no modification required.
• Diamond slotted design increases brake pad bite, extends pad life, and serves as a rotor wear indicator.
• Precision-drilled holes and countersunk design help prevent cracking and build-up, enhance ventilation and dissipate heat for smoother, quieter stopping.
• Break-in note: rotors arrive fully covered in the black zinc coating; the coating on the braking surface wears off during initial bedding, leaving the hub and inner vane structure coated.
