Stoptech Sport Pack-Drilled/Slotted Front Brake Rotor Kit

This is a great way to improve the braking performance and stopping capacity to your Subaru STI. This kit will include Stoptech's Drilled and Slotted Front Brake Rotors as well as a set of their Posi-Quiet Brake Pads. This combination makes for a great performance upgrade as drilled and slotted rotors will wipe the contact surface of the rotor clean from brake dust and hot braking gases. And they are combined with an excellent street brake pad that is not too harsh, and they are also low-dust, low-noise, as well as low-vibration. 

These are direct replacements for your front brake rotors and pads and are ideal for daily driver use, and for the occasional weekend track event.
