I put the Zimmerman rotors on my 323i years ago and wasn’t real happy with them. They seamed to rust on the hub and I did have a shimmy when braking. Not sure if that was from the brakes or the suspension. Traded it for my ZHP before finding out.
On the pads, I’m currently running Hawk Performance’s High Performance Street 5.0.
