StopTech 121.44183 Sport Blank Disc Brake Rotor

The StopTech 121.44183 is a Sport blank disc brake rotor engineered as a direct OE replacement that delivers improved performance over standard factory rotors. Designed to work with your existing factory brake calipers and hardware, this rotor provides a precise, no-hassle fitment with a meaningful upgrade in braking capability.

StopTech Sport rotors are manufactured from high-quality iron castings with superior metallurgy that promotes cooler operating temperatures, quieter braking, and enhanced crack resistance compared to economy-grade replacements. The smooth, blank friction surface is ideal for street driving and pairs effectively with a wide range of OEM and aftermarket brake pad compounds.

Key Features:

• Direct OE replacement — bolt-on fitment using factory calipers and hardware
• Black E-coat finish — electrostatically applied coating withstands up to 400 hours of saltwater exposure for long-lasting corrosion protection on the hat and cooling vanes
• High-carbon metallurgy — improved resistance to cracking under thermal stress, reduced noise and vibration (NVH)
• Engineered vane design — promotes efficient heat dissipation for consistent brake performance during repeated stops
• Smooth blank surface — clean friction interface compatible with street and performance brake pad compounds
• OEM dimensions — matches factory rotor diameter and thickness for straightforward installation

StopTech is a USA-based manufacturer with a motorsport heritage, and all Sport rotors are produced to meet rigorous performance and dimensional standards. The 121.44183 is a cost-effective performance upgrade for drivers seeking OEM-or-better reliability and braking feel.
