Description
Upgrade your vehicle’s braking system with the StopTech Part Number 126.40097SL Sport Slotted Rear Left Brake Rotor, designed specifically for 2017 to 2020 Honda Civic SiR models. These high-performance, one-piece rotors are a direct replacement for factory discs, offering a seamless fit and enhanced braking capabilities. The unique slotting pattern helps with heat dissipation, brake dust removal, and gas evacuation, which results in reduced brake fade and improved overall stopping power. This design also minimizes pad glazing, providing consistent pedal feel and increased bite under both dry and wet conditions. Constructed with advanced high carbon metallurgy and protected by a durable black e-coating, these rotors are engineered for longevity, corrosion resistance, and quieter operation. The double disk grinding process ensures a uniform friction surface, contributing to smoother braking performance and extended rotor life. The directional curve vane design on selected applications optimizes airflow, further aiding in thermal management during aggressive driving. Cryogenic treatment reduces residual stress, enhancing crack resistance and durability over time. Whether you’re upgrading for street performance or spirited driving, these rotors deliver superior resistance to thermal cracking and maintain high performance even under demanding conditions. Designed as a direct OE replacement, they integrate seamlessly with your OEM brake calipers and pads, especially effective with higher friction European-style brake pad compounds. These performance rotors combine style, function, and reliability, making them an excellent choice for Honda Civic owners seeking improved braking performance and enhanced aesthetics behind their wheels.
