4-Wheel Disc Brake Kit with Cross-Drilled Slotted Rotors

The R1 Concepts WHUH2-59066 is a comprehensive 4-wheel disc brake kit engineered as an OE replacement for drivers seeking increased brake performance over stock. This kit includes four high-performance brake rotors and eight performance brake pads, along with necessary hardware. The rotors are constructed from G3000 grade cast iron and feature a black zinc finish for superior rust protection and corrosion resistance. They are precision-drilled and countersunk to prevent cracking, enhance ventilation, and dissipate heat effectively for smoother, quieter stopping and longer life. The included Optimum OEp brake pads are formulated for low dust and noise, featuring shims to eliminate vibration and squeal. These asbestos-free pads offer excellent fade resistance, making them a top choice for front and rear brake pad replacement during normal commutes. The kit is designed with multiple alloys for improved heat dissipation and performance, with mill-balancing ensuring proper rotor function and quality validation for correct metallurgy and brake plate thickness.
