Andrew, The pads that came in the box had part numbers. The pad that came shrink wrapped have no part numbers or anything to indicate that they are rotex gold pads. I called "John" at brakeworld and his story is this - The pads were rushed to them (many on back-order) so sometimes they don't put them in boxes. I'm just wondering if they are seconds - no box, no part numbers, no company name. I put them on the car today and they did fit. It took me a little while to figure out how to pull the back pads but I did figure it out. Never have seen that set-up before. To the forum member waiting for his pads John said they got in 12 sets so you might want to give him a call to see if yours are shipped. Let me know if your front pads come in a box or not too. Anyway what do you think about pads with no type of I.D. on them.
