STOPTECH 126.47022SL Brake disc (front left) Power Slot Subaru 2005+ Sti Slotted

Here, is PowerSlot’s slotted front rotor. He slots provide an escape from excessive heat gasses that could potentially resonate within your brake pads. As the brake pad wears down, the used friction material turns into a fine dust. This layer of dust, heat, and gas can build up between the pad and the rotor which can reduce braking performance. 
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.
