The StopTech 126.40097SR is a high‑performance rear right slotted brake rotor engineered as a direct replacement for the factory rotor on select 2017–20 Honda Civic Si models. Its precision‑machined slots enhance pad bite and help channel heat, brake dust, and gases away from the pad‑to‑rotor interface, resulting in more consistent braking response and reduced fade under repeated braking. The high‑carbon metallurgy enhances rotor strength and resistance to cracking under thermal stress, while the black e‑coating on non‑friction surfaces helps protect against corrosion and extend service life.
Designed for seamless compatibility with original equipment rear calipers and brake hardware, the 126.40097SR delivers dependable stopping power and improved brake modulation for daily driving or spirited street use. Whether refreshing worn rotors or upgrading for better everyday braking confidence, this StopTech rotor offers a durable and performance‑oriented solution. Always verify fitment with your vehicle’s exact year, trim, and engine before installation.
