R1 Concepts WBUH2-45016 Carbon Series Drilled & Slotted Front and Rear Brake Kit with Optimum OEp Pads

The R1 Concepts WBUH2-45016 is a complete front and rear brake kit from R1 Concepts' Carbon Series, delivering upgraded stopping power with drilled and slotted rotors paired with Optimum OEp brake pads and all necessary hardware — everything needed for a full brake system replacement in one box.

Key Features:

• Complete All-in-One Kit: Includes (4) high-performance drilled and slotted brake rotors, (8) Optimum OEp brake pads, and hardware for a full front and rear replacement
• G3000 Grade Cast Iron Rotors: Manufactured to OEM specifications with rust-protective carbon coating for long-lasting durability and corrosion resistance
• Drilled & Slotted Design: Precision-drilled holes with countersunk design prevent cracking and buildup, while diamond slotting enhances brake pad bite, improves heat dissipation, and acts as a wear indicator
• Non-Directional Rotor Finish: Promotes faster, more even brake pad bed-in for quieter, smoother stops right out of the box
• Optimum OEp Brake Pads: Advanced low-copper formulation meets California and Washington environmental restrictions for 2021/2025; asbestos-free with excellent fade resistance
• Low Dust & Quiet Operation: Pads include shims to eliminate brake noise and minimize brake dust for cleaner wheels
• Direct Fit: Engineered to OEM specifications — no modifications required for installation
• Enhanced Carbon Alloy Formula: Increased carbon, molybdenum, and chromium content improves noise dampening, heat management, and long-term strength
