I recently changed from Pagid to ATE Teves pads on my 300E. The only difference that I see so far (<1K miles) is the pedel effort seems a little higher and I have heard a slight squeel twice, both times during the first stop on a very cold day (-9 and 4 degrees). They seem OK otherwise. I also put in the standard ATE rotors.
