Those Akebono ceramic pads are great. I put those same pads, size 325 per Hawk, on the 535 last week. Those front pads are for the e38, e39, x5 fronts, & 850i fronts. They fit well and are very quiet. I have the 850i single piston front brakes on the 535.
The Hawk ceramics that were on there had glazed & become very noisy. The Ate rotors from BMA weren't that great. The runout was ok, once I scraped off a bunch of sticky junk. I had to sand down 1 spot, as the razor blade wasn't working.
