Keep confident, quiet braking on your 2015-2021 Subaru WRX with the Beck/Arnley Disc Brake Rotor, MPN 083-3706. This is a rear rotor engineered as a direct replacement for the original equipment on the listed application, with attention to form, fit, and function so it drops in like the factory piece and works with your existing pads.
Application-specific for this vehicle, so you install the right part with confidence. Signs a rotor may need replacing include pulsation or vibration through the pedal, deep scoring, or excessive lateral runout. Rotors are sold individually and this listing is for one; replacing both rear rotors together as a matched pair is recommended for even, balanced braking.
Fitment: 2015-2021 Subaru WRX. See the Buyer's Guide tab for engine-level details.
