I have a 2006 Mustang GT with a Saleen Supercharger. This is my daily driver, and I never drive on any type of road course or 1/4 mile tracks. I'm changing the brakes here soon and I have a set of Wagner thermo quiet brake pads. I can't stand spending money on stock rotors that are going to rust. The stock rotors have worked fine, but I just done like the rust. Will I be wasting my money if I decide to get them. They really nice. Can you use any brake pad with the slotted rotors?
