I bought the Power Stop cross drilled and slotted rotors for my 2000 Mustang GT (Built motor, suspension, and rear end). They were delivered right as expected, and AutoAnything has always been delightful to order from. Once they arrived, The rotors were in great condition, and easily labeled right and left side. Installation was a breeze, but pending on your application and mechanical knowledge, I would recommend you know what your doing especially dealing with your brakes. I also installed stainless steel brake lines at the same time. Now, the Rotors were stamped “China”, but what would you expect for the price. after install (1 hr total: also put Hawk HPS pads) I could notice a considerable difference in the smoothness and the brakes biting. It’s been about two weeks since I’ve had them on my car. I’ve taken them (light) road racing, drag racing, hard stops from 110 mph, and wet and dry stops. The brakes have held up with minimal to no fade, sloppiness, or rough stops. I am very impressed that something made in China is this decent. Granted it’s only been about two weeks, and the Stainless steel lines helped too, but The rotors show no signs of deteriorating. I am very pleased with this purchase.
