Stoptech Slotted Front Rotors | 2015-2017 Subaru WRX STI
The Power Slot’s exclusive Vac-U-Slots are machined into the rotor, and help expel gasses, dust, as well as heat. This will also help keep the surface of the brake pad clean, And in wet conditions, the PowerSlot Vac-U-Slot helps push the water off the braking surface for increased stopping power.
This is a great OEM replacement suitable for both track, and street conditions.
