This part cross-references Centric Parts 120.47032 and Raybestos Brakes 982044 for the same application. It also aligns with Subaru WRX rear rotor applications across 2015-2021 model years, including 2020 WRX with 1-piston rear caliper and 2021 WRX without EyeSight Technology.

What This Rotor Set Helps Address

• Brake fade from heat buildup during repeated stops
• Rust and surface corrosion on exposed rotor faces
• Dust and moisture buildup on the braking surface
• Uneven pad contact caused by worn or damaged rear rotors
• Restoring rear braking response on Subaru WRX models
