StopTech Sport Drilled & Slotted Rear Left Rotor Part #127.34145R for BMW 3 Series and 4 Series

Description

Upgrade your BMW’s braking system with the StopTech Sport Drilled & Slotted Rotor Part #127.34145R, designed specifically for models including the BMW 328i, 428i, M235i, and 228i from 2012 to 2016. These high-performance rotors are engineered as a direct replacement for your factory discs, ensuring a seamless fit and enhanced braking capabilities. The combination of cross-drilling and slotting improves heat dissipation and brake dust removal, which helps maintain consistent stopping power and reduces the risk of brake fade during aggressive driving or heavy braking conditions. The aesthetic appeal of the drilled and slotted design also provides a sportier look behind your wheels, elevating the overall appearance of your vehicle.
Constructed from advanced high-carbon metallurgy, these rotors feature a durable black e-coating that offers superior corrosion resistance, ensuring longevity even in harsh driving environments. The double disc ground process ensures a uniform friction surface, contributing to consistent brake feel and performance. Incorporating proprietary Molybdenum and Chromium alloys, these rotors resist cracking from thermal stress, which is critical for maintaining structural integrity under high temperatures. The design includes directional curve vane patterns on selected applications, which enhance airflow and heat dissipation, further improving brake performance during demanding driving situations.
Designed to work optimally with European-style brake pad compounds, especially those with higher friction coefficients, these rotors provide increased initial bite and improved wet weather response. Their features include a non-friction black e-coating for corrosion protection, crack resistance, and reduced pad squeal. As a direct OE replacement, these rotors provide a reliable upgrade option for enhancing your vehicle’s stopping power and aesthetic appeal without the need for modifications. Whether for daily driving or spirited driving, the StopTech Sport Rotors are engineered to deliver consistent, high-performance braking for your BMW.
