I installed these discs on my 2006 Mustang with Hawk HPS pads (EBC pads were much more expensive). I drove this combo 80,000 miles before they both needed replacing. This included two autocross seasons. The black oxide coating keeps rust to a minimum. Braking performance outdoors is consistently excellent, even in wet or snowy conditions. Experienced course instructors were surprised at how effective my brakes were on such a relatively heavy machine. Braking feels like cicadas are swarming around the car, but the crisp but gentle braking is worth the small noise. At 140,000 miles I replaced all 4 corners with the same brake combo and reinforced stainless cables. We look forward to another exciting 80,000 miles!
