R1 Concepts Brake Rotor Drum- Blank Fits Mazda 626

R1 Concepts eLINE Black Series Drilled & Slotted Brake Rotors are designed for drivers seeking increased brake performance with rust protection. They are made of G3000 grade cast iron with a zinc finish for ultimate rust protection and are built to OEM specifications, requiring no modification. The precision-drilled holes and countersunk design prevent cracking and buildup, enhance ventilation, and dissipate heat, resulting in smoother, quieter, and longer-lasting consistent braking performance. The diamond slotted design increases brake pad bite, extends brake pad life, and serves as a rotor wear indicator. This is an all-in-one complete front and rear brake kit replacement that comes with four high-performance brake rotors.
