StopTech Sport Drilled & Slotted Rear Left Rotor for BMW 335i, 340i, 435i, and More – Part #127.34144L

Description

Upgrade your BMW’s braking system with the StopTech Sport Drilled & Slotted Rear Left Rotor, part number 127.34144L. Designed as a direct replacement for factory brake discs, these one-piece rotors combine advanced metallurgy with precision machining to deliver improved stopping power and durability. The unique cross-drilling and slotting facilitate efficient heat dissipation, brake dust removal, and gasses venting, ensuring consistent performance under demanding driving conditions. These features help prevent brake pad glazing and enhance both wet and dry braking response, providing confident stopping in various weather conditions.
Constructed with high-carbon materials and protected with a black e-coating, the rotors offer excellent corrosion resistance and quieter operation. The added Molybdenum and Chromium in the alloy reinforce the rotor structure, reducing the likelihood of cracking from thermal stress and extending service life. The double disc ground finish ensures a uniform friction surface for predictable braking feel and improved initial bite, especially effective with high-friction European-style brake pads. Selected applications feature directional curve vane designs that improve airflow and cooling efficiency, further enhancing the rotor’s thermal management.
These rotors are compatible with a range of BMW models including 2013 to 2016 BMW 335i, 2014 to 2018 BMW 340i, 2015 to 2016 BMW 435i, and 2017 to 2020 BMW 440i, among others. They are designed to meet or exceed original equipment specifications, making them a reliable choice for enthusiasts and daily drivers seeking superior braking performance. The product is a non-CARB approved, air freight-prohibited item, and comes with a Prop 65 warning for safety compliance. Enhance your vehicle’s braking capabilities with the StopTech sport rotors that combine innovative engineering with durable construction for maximum performance and longevity.
