Don, installed Zimmerman front rotors on my son's 2005 BMW 745i recently. The rotors were high quality and were coated with a gray primer, just like rotors bought from a MB dealer. I would opt for the Zimmerman rotors.

There is no need to touch the wheel bearings. Simply remove the set screw and separate the rotor from the hub. You may have to pursuade the rotor with a hammer since they sometimes rust to the hub.

the w124 rotor comes off that easy? I thought the w123/124/126 were the same. I did the rotors on my w126 and I had to remove the hub, put the thing in a vice and remove the bolts on the rear of the disc to separate the two

Not on a W124. I just did the rotors on mine, just a set screw. I had to beat the **** out of the to get them to brake free. I even had to get a BFH, the mallet wasn't doing a thing. Good thing I was replacing them.

Just to relate to the subject, I'm redoing most of my 300Es brake system. Rotors, pads, calipers, hoses, all the rear steel lines and parking brakes.
I used ATE rotors & pads on the back, Centric rotors & bendix pads on the front. The calipers were all Centric rebuilds which turned out to be from OEM Girling & ATE cores. I paid the $96 for the 3 rear factory steel brake lines assuming they would be pre-bent. They weren't, so I'm returning the the two short L & R ones ($14 @ the parts store) but I'm going to use the ($38) factory line that routes to the rear as store doesn't have a single line that long.
My parking brake was in pretty bad shape, lots of rust with the shoe material crumbling and falling apart.

I hope using Centric wasn't a mistake, I have no experience with them.

awesome, that makes the job so much easier. I'll put some anti seize on the back of the new rotors so they don't rust themselves to the hub

make sure the emergency brake is released before you do the rears!

just doing the fronts. Rears still have life left in them

Don, unless you drive extremely aggressively or race your car vented front rotors should be fine. Don't see the need for drilled or slotted rotors for everyday normal driving.
