StopTech AeroRotor Replacement Kits ARK - 129.39038.13

Upgrade your vehicle's braking system with the StopTech AeroRotor Replacement Kits ARK, specifically designed for those looking to enhance their driving experience while retaining the original factory brake calipers. This product is engineered to deliver superior performance compared to standard rotors, making it an excellent choice for both everyday driving and spirited track sessions.

Key Features

  • Position: Front Left
  • Style: Slotted
  • Weight Reduction: Up to 8 pounds lighter than stock rotors
  • Thermal Performance: Improved thermal capabilities and optimized heat dissipation
  • Compatibility: Designed to work seamlessly with OE calipers

Performance Benefits

The StopTech AeroRotors feature a patented internal vane design that enhances airflow, pushing up to 80% more air compared to factory rotors. This significant increase in cooling efficiency helps to reduce brake fade, especially during high-performance driving scenarios. The unique floating design of the AeroRotors allows for independent expansion of the rotor and hat, preventing distortion and maintaining consistent braking performance.

Lightweight Design

By utilizing aircraft-grade aluminum for the AeroHats, these rotors significantly reduce unsprung and rotational mass. This not only contributes to faster acceleration and deceleration but also improves overall vehicle handling, making your driving experience more responsive and enjoyable.

Heat Management

With the option for slotted or cross-drilled designs, these rotors effectively dissipate heat, friction material, and debris. This ensures that fresh pad material consistently contacts the rotor surface, enhancing braking efficiency and reliability. For those in colder climates, an optional anti-corrosion zinc finish is available, protecting against rust and extending the lifespan of your rotors.

One driver mentioned, "I felt an immediate difference in how my car handles during hard braking. The rotors stay cooler, and I can really feel the improved stopping power, especially on the track."
