Slotted Brake Rotor Conversion

Recently we had a really nice Subaru WRX come in to our shop to have the stock rotors converted to slotted ones. Along with the conversion of their rotors,  they had us replace their brake hoses with stainless steel braided brake hoses.

What are some advantages of slotted rotors?

The rotor is lighter, therefore it decreases it’s rotational inertia.
The slots promote out-gassing and aid in removing debris that may build up between the pad and rotor surface.
Wet performance is enhanced.
