Stoptech Drilled & Slotted Rear Brake Rotors

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

127.63064L / 127.63064R

Overview:

Upgrade your braking system with Stoptech Drilled & Slotted Rear Brake Rotors designed specifically for the Chrysler 300C, Dodge Challenger, Charger, and Magnum SRT8 models from 2006 through 2024. Engineered for vehicles equipped with the powerful 6.1L or 6.4L HEMI engines, these rotors deliver enhanced stopping power, improved heat dissipation, and superior durability. Ideal for enthusiasts seeking reliable performance and a sporty aesthetic, these rotors provide a direct replacement for factory discs while elevating your vehicle’s braking capabilities.

Stoptech’s drilled and slotted design helps to quickly evacuate heat, gases, and debris from the braking surface, reducing brake fade and maintaining consistent pedal feel during aggressive driving or heavy braking scenarios. Whether you’re upgrading your daily driver or enhancing a track-ready build, these rotors offer a balanced combination of performance, longevity, and style.

Key Features:

Stoptech Drilled & Slotted Rear Brake Rotors incorporate advanced engineering and materials to optimize braking performance and reliability. Key features include:

• Precision CNC-machined using CAD-CAM technology for perfect balance and alignment
• Drilled holes and slots designed to purge hot gases and brake dust, improving pad contact and reducing fade
• Black e-coating on rotor hats and cooling vanes for superior corrosion resistance, withstanding up to 400 hours of saltwater exposure
• Power Alloy metallurgy with enhanced molybdenum and carbon content for increased hardness and tensile strength
• Directional vane design to maximize cooling efficiency without compromising structural integrity
• Non-directional finish to reduce break-in time and ensure immediate performance
• Lightweight construction to reduce unsprung weight, improving handling and ride quality
• OEM-spec fitment for hassle-free installation and compatibility with factory hardware
• TÜV-certified quality and durability, meeting rigorous German automotive standards

Construction & Design:

These Stoptech rotors are crafted from high-grade cast iron using proprietary Power Alloy metallurgy, which enhances rotor strength and wear resistance. The manufacturing process includes controlled cooling rates and precise alloy composition to achieve optimal hardness and tensile strength, ensuring long-lasting performance under demanding conditions.

The rotors feature a drilled and slotted surface pattern that is carefully engineered to avoid contact between drilled holes and cooling vanes, preserving structural integrity while maximizing heat dissipation. The black e-coating applied electrostatically covers both sides of the rotor hat, the cooling vanes, and the outer edge, providing excellent protection against rust and corrosion, especially in harsh weather or road salt environments.

Performance & Sound

Stoptech’s drilled and slotted design enhances braking performance by eliminating the gas layer that can form between the brake pad and rotor during heavy braking, restoring full pad-to-rotor contact instantly. This results in improved initial bite and consistent stopping power, even during repeated hard stops. The slots also help clear debris and water from the rotor surface, maintaining effective braking in wet conditions.

Additionally, the rotors contribute to a confident brake pedal feel and reduce the likelihood of brake fade, making them suitable for spirited street driving and occasional track use. The design also helps minimize brake noise and vibration, delivering a smooth and controlled braking experience.

Installation & Fitment:

Stoptech Drilled & Slotted Rear Brake Rotors are designed as direct replacements for the factory rear rotors on Chrysler 300C, Dodge Challenger, Charger, and Magnum SRT8 models equipped with 6.1L or 6.4L engines from 2006 to 2024. They install easily using existing mounting points and hardware, requiring no modifications or special tools. This ensures a straightforward upgrade process that maintains factory fitment and brake system integrity.

What's Included:

• One Left Rear Stoptech Drilled & Slotted Brake Rotor (Part #127.63064L)
• One Right Rear Stoptech Drilled & Slotted Brake Rotor (Part #127.63064R)

Ideal For:

These rotors are perfect for drivers who want to enhance the braking performance and appearance of their Chrysler 300C, Dodge Challenger, Charger, or Magnum SRT8 without the expense of a full big brake kit. They suit enthusiasts who demand reliable stopping power for spirited street driving, occasional track days, or improved safety in daily driving conditions. Additionally, they complement Stoptech Big Brake Kits for a cohesive, high-performance brake upgrade.

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.
