I'm two months in now with the Porterfields and they squeak, maybe not as grindingly as stock, but they aren't anything close to silent. Yes, I did bed them and I had the install done by a local high end aftermarket shop. I had exactly 5 blissful days of quiet braking before that wrenching sound began again. Of course, it helps to wash them thoroughly, which will give me a day or two of relief, but this didn't solve the problem.
