FactionFab products are the result of where quality engineering meets excellent manufacturing processes. These are the FactionFab Swept Slot Bi-Directional Rotors and offer excellent performance on the street, and they will perform well for light track use. If your current rotors need replacing and you want something that offers better performance then you will be happy with this purchase. 

These rotors feature FactionFab's sharp-edged grooves on the face of the rotor. These will wipe the surface of the rotor clean from any brake dust, residue, or hot brake gases under spirited use. This will keep the surface of the rotor clean for consistent contact with the brake pad. Another great feature is the black E-coating to help fight corrosion as your brake rotors experience all elements of the road. They are also dual-drilled for those of you who may upgrade to the larger 2018+ STI calipers.

These rotors are sold as a pair and will fit the rear location of your vehicle.
