StopTech Part Number 126.34144SR Sport Slotted Brake Rotor for BMW 335i, 435i, and 340i Models

Description

Upgrade your BMW’s braking system with the StopTech Part Number 126.34144SR Sport Slotted Brake Rotor, designed specifically for 2013-2016 BMW 335i, 2014-2016 BMW 435i, and 2017-2020 BMW 440i models. These high-performance, one-piece rotors are direct replacements for your factory discs, providing an excellent balance of improved braking power and durability. The slotted design effectively disperses heat, brake dust, and gases to enhance stopping performance in both wet and dry conditions. The slots also help prevent brake pad glazing, ensuring consistent friction and pedal feel during spirited driving or daily commuting.

The rotors feature a premium black e-coating that offers superior corrosion resistance, extending the lifespan of your braking components. Constructed with advanced high-carbon metallurgy, these rotors are engineered for quieter operation, increased crack resistance, and enhanced thermal stress durability. The inclusion of Molybdenum and Chromium in the alloy composition helps resist cracking, even under demanding driving conditions. Double disk grinding ensures a smooth, consistent friction surface, contributing to predictable brake response and reduced noise. These rotors are ideal for European-style brake pad compounds and are compatible with higher friction pads, offering increased initial bite and improved response in wet weather.

Designed as direct OE replacements, the StopTech Sport Slotted Rotors are easy to install and provide a significant upgrade over stock components. The directional curve vane design on selected applications improves airflow and cooling efficiency, reducing thermal stress during hard braking. Cryogenic treatment further reduces residual stress within the rotor material, enhancing longevity and performance. Whether for spirited driving, track days, or everyday use, these rotors deliver consistent braking performance and reliable protection against corrosion and heat-related damage.
