StopTech Sport Drilled & Slotted Rear Left Rotor

Experience a significant upgrade in braking performance with the StopTech Sport Drilled & Slotted Rear Left Rotor. Engineered for discerning drivers, these rotors are designed to replace your factory discs, offering enhanced stopping power, superior heat management, and a visually appealing performance look.

Unleash Superior Braking Performance:

  • Advanced Heat Dissipation: The combination of precision drilling and slotting allows for efficient expulsion of heat, gases, and brake dust. This prevents rotor and pad overheating, minimizing brake fade and ensuring consistent performance during aggressive driving.
  • Improved Pad Grip: Slots create additional surfaces for the brake pads to engage with, resulting in a sharper initial bite and more responsive braking in both wet and dry conditions.
  • Enhanced Durability: Constructed with high-carbon metallurgy, these rotors offer increased strength, reduced noise, and superior resistance to thermal cracking, ensuring longevity and reliability under demanding use.
  • Corrosion Protection: A durable black e-coating provides excellent protection against rust and corrosion, maintaining the rotor's aesthetic appeal and structural integrity throughout its lifespan.
  • Direct Fit Replacement: Designed as a direct replacement for the factory rear left rotor, ensuring a hassle-free installation process and perfect compatibility with your vehicle's existing brake system.

This StopTech Sport Rotor is suitable for a wide array of BMW models, including the 335i, 340i, 435i, and their variants from 2013 onwards. Whether you're upgrading for spirited driving, track days, or simply seeking a more robust daily braking solution, these rotors deliver exceptional performance and value. Trust StopTech for braking components that combine cutting-edge technology with proven reliability.
