Stoptech Slotted Brake Rotors

2006–2024 Chrysler 300 / Dodge Challenger / Charger / Magnum SRT8 6.1L & 6.4L

126.63064SL / 126.63064SR

Overview:

Stoptech Slotted Rear Brake Rotors are engineered to enhance braking performance and cooling efficiency for Chrysler 300C, Dodge Challenger, Charger, and Magnum SRT8 models equipped with 6.1L or 6.4L engines from 2006 through 2024. Designed as a direct replacement for factory rotors, these slotted rotors improve pad bite and help maintain consistent braking under demanding conditions. Ideal for enthusiasts seeking a reliable upgrade that combines performance, durability, and style, these rotors also complement Stoptech’s Big Brake Kits for a cohesive brake system appearance.

Whether you drive your vehicle daily or push it on the track, these rotors provide improved heat dissipation and debris removal, reducing brake fade and extending pad life. The slotted design actively sweeps away dust, gas, and water from the pad surface, ensuring optimal contact and consistent stopping power.

Key Features:

Stoptech Slotted Brake Rotors incorporate advanced engineering and materials to deliver superior braking performance and longevity. Key features include:

• Precision-machined slots that enhance pad bite and help clear debris from the rotor surface
• Black e-coating on the rotor hats, cooling vanes, and edges for corrosion resistance and long-lasting finish
• Power Alloy metallurgy with optimized molybdenum and carbon content for increased hardness and tensile strength
• Directional slot patterns tailored for left and right sides to maximize cooling and performance
• Unique cooling vane designs that improve airflow and heat dissipation during heavy braking
• TÜV-certified quality ensuring rigorous testing for performance, durability, and fitment
• Direct bolt-on fitment for 2006–2024 Chrysler 300, 2008–2023 Dodge Challenger, 2006–2023 Dodge Charger, and 2005–2008 Dodge Magnum SRT8 models
• Compatible with Stoptech Big Brake Kits for a complete brake upgrade solution
• Free shipping and fast dispatch within 24-48 hours

Construction & Design:

These rotors are crafted using Stoptech’s proprietary Power Alloy metallurgy, which involves precise control of alloy composition and cooling rates during casting. This process enhances the rotor’s hardness and tensile strength, resulting in improved wear resistance and durability under high-stress braking conditions. The rotors feature a black e-coating applied electrostatically to critical areas including both sides of the rotor hat, inside the cooling vanes, and the outer edges. This coating protects against rust and corrosion, even after 400 hours of saltwater exposure, preventing lateral runout issues caused by rust buildup.

The slotted design is carefully engineered with directional patterns that differ between left and right rotors, ensuring that slots never intersect cooling vanes. This maximizes structural integrity and cooling efficiency, while the straight or pillar vane designs optimize airflow to reduce heat buildup during aggressive driving or track use.

Installation & Fitment:

Stoptech Slotted Rear Brake Rotors are designed for direct replacement of factory rear rotors on compatible Chrysler 300, Dodge Challenger, Charger, and Magnum SRT8 models with 6.1L or 6.4L engines. Installation requires no modifications and fits perfectly with OEM brake pads and calipers. These rotors are ideal for enthusiasts upgrading their braking system for improved performance, whether paired with stock components or Stoptech’s Big Brake Kits.

What's Included:

• One left rear slotted brake rotor (Part #126.63064SL)
• One right rear slotted brake rotor (Part #126.63064SR)

Ideal For:

These rotors are perfect for drivers who demand enhanced braking performance and reliability from their Chrysler 300C, Dodge Challenger, Charger, or Magnum SRT8. Whether you are upgrading for spirited street driving, occasional track days, or simply want to improve the aesthetics and function of your brake system, Stoptech Slotted Brake Rotors offer a balanced solution that combines durability, cooling efficiency, and aggressive styling.

Stoptech produces brake kits, pads, rotors, and hydraulic components. For performance driving, heat management and confident stopping is key—especially when speeds rise and repeated stops generate heat. Whether you’re improving street braking feel or preparing for track duty, Stoptech components help deliver consistent, confidence-building braking performance.
