StopTech Slotted Sport Brake Rotors for BMW 3 Series

Enhance your vehicle's braking system with StopTech Slotted Sport Brake Rotors, designed as a direct replacement for your factory setup. These rotors are specifically engineered for a range of BMW 3 Series models from 1984 to 1991, including the 318i, 318is, 325, 325e, 325es, 325i, 325is, and 325iX. They provide a noticeable improvement in braking performance and heat management.

Key Features and Benefits:

  • Superior Heat Dissipation: The precisely engineered slots help to vent heat and gases away from the rotor surface, reducing the risk of brake fade and extending the life of your brake pads.
  • Improved Pad Performance: Slotting helps to keep the brake pad surface clean and consistent, ensuring optimal contact and bite for more responsive braking in both wet and dry conditions.
  • Durable E-Coating: A protective black e-coating is applied to prevent corrosion and rust, ensuring a clean appearance and long-lasting performance.
  • High-Carbon Metallurgy: Featuring high-carbon content in most applications, these rotors offer enhanced durability, reduced noise, and better resistance to thermal cracking.
  • Easy Installation: As a direct-fit component, these rotors are designed to install easily onto your existing brake system without modifications.

Vehicle Fitment:

  • BMW 318i: 1991
  • BMW 318is: 1991
  • BMW 325: 1986-1988
