StopTech 121.34099 Plain Sport Stop Disc Brake Rotor

The StopTech 121.34099 is a plain-faced Sport Stop disc brake rotor engineered as a direct OE replacement. Designed and developed by StopTech — the high-performance and racing division of Centric Parts — this rotor delivers reliable, consistent stopping power for daily driving and performance street use.

Key Features:

• Plain rotor face: Smooth, flat friction surface provides consistent, quiet braking for street and light-performance applications
• High-carbon metallurgy: Proprietary alloy formulation resists thermal cracking and reduces noise, vibration, and harshness (NVH)
• Black e-coat finish: Electrostatically applied coating protects the hat and cooling vane areas against corrosion, tested to withstand 400 hours of saltwater exposure
• Optimized vane design: Internal cooling vanes promote airflow through the rotor to manage heat buildup and extend rotor and pad life
• Direct-fit replacement: Engineered to bolt directly onto factory brake systems with no modifications required
• OEM-quality standards: Precision machined to tight tolerances for proper fitment and smooth, vibration-free operation

The StopTech 121.34099 is an excellent choice for drivers seeking a dependable, long-lasting brake rotor upgrade that pairs well with a wide range of street performance brake pads. It is sold as a single rotor.
