i dont trust it personally, anyone can take a regular rotor, drill some holes in it and mill some slots. Doesnt make it a high performance product by any means. if your just going for looks then they're perfect but for real performance you want to go with a more reputable source such as brembo. with 15000 miles on a pair of rotors its clear that they were not used very hard. My Brembo rotors dont last more that a couple thousand miles til theyre replaced, but i drive the S*** out of them. It really depends what you are looking for in the product that will determine where you should get them. ALSO! cross drilled rotors are not ideal for any performance application. Purely slotted rotors would be the way to go. Any real track car or performance vehicle will have slotted rotors or cast vented (these are the rotors that you see on porsche, mercedes, ferrari etc) these rotors have the holes but they are NOT drilled. The rotor is actually cast that way. when ever a rotor has holes drilled in it the holes become weak spots and they are the perfect breeding ground for cracks and fissures. If you are after performance braking you should look at extra thick solid rotors or slotted rotors from a reputable source. The quality of the metal makes a huge difference in when and how easy the rotor heats up, stops, or warps. In the end its best to just spend the money on a quality rotor with a quality pad that suits your application.
