StopTech 13-15 BMW 335i Drilled Front Left Sport Brake Rotor - 128.34144L

StopTech Drilled Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance.

About Stoptech-

StopTech is a prominent manufacturer of high-performance braking systems and components, founded in 1999. The company's vision was clear from the outset: to design and produce top-tier brake systems for both street and track use, combining performance with reliability. StopTech has since grown to become a recognized leader in the brake industry, known for its cutting-edge technologies and contributions to motorsport.

Stoptech Key Features

• Balanced Brake Upgrades: StopTech revolutionized the aftermarket brake industry by being the first company to offer Balanced Brake Upgrades. This innovation involves upgrading the vehicle’s front brakes while ensuring compatibility with the rear original equipment (OE) brakes. This approach provides better overall braking performance by optimizing brake balance, rather than just improving front or rear braking force independently. These systems significantly enhance braking power, reduce fade, and increase overall safety and performance, particularly in high-stress situations like racing or aggressive street driving.

• Racing DNA: With motorsport at its core, StopTech has established itself as a leading supplier of brake systems in competitive racing environments. The company has a notable presence in series such as the SPEED World Challenge® Touring Car Series and the Grand-Am® Cup. The high-performance brake systems they offer are designed to withstand the extreme demands of racing, providing drivers with superior stopping power and control.

• Manufacturing Excellence: All StopTech products are engineered and manufactured at the company’s facilities in Southern California, utilizing ISO-certified standards. The parts are machined with the latest CNC (Computer Numerical Control) machines, which feature active tooling to ensure precision and quality. The brand’s commitment to quality is further affirmed by the approval of many of their products from TÜV, a leading European certification organization, which guarantees adherence to strict safety and quality standards.

• Focus on Innovation: StopTech has remained at the forefront of braking technology through continuous innovation. The company strives to push the boundaries of braking performance, with an emphasis on improving safety, durability, and heat dissipation—critical factors in high-performance braking. As part of this, StopTech continues to refine its brake pads, rotors, calipers, and fluid, ensuring their products remain competitive and effective in demanding conditions.

What Stoptech Offers

StopTech’s product range includes:

• Big Brake Kits (BBKs): These kits offer larger, more powerful brakes to improve overall performance and heat dissipation.
• Brake Pads: A variety of high-performance compounds are available for both street and track applications, designed to optimize braking power while minimizing fade.
• Rotors: StopTech produces slotted, drilled, and solid rotors designed for improved heat dissipation and performance.
• Calipers: The company manufactures both lightweight and heavy-duty calipers to suit different types of vehicles and racing needs.
• Brake Fluids: High-performance fluids designed to withstand extreme temperatures and maintain braking performance under stress.
