It's easy to put balance weights in between the fins on a vented rotor. Solid rotors and drums are tougher - drums require welding, solid rotors require drilling holes.|

I have an old Bear spinner wheel balancing Machine, It has a couple sets of mounting plates with multiple holes for different wheel patterns. When you can't match up the bolt holes there are a couple cones with a one inch bore used to mount a brake rotor or hub, Static balance is easy. To spinn balance a rotor I would have to change out the steel driver wheel that contacts the tire . I have seen quite a few rotors with large Roll pins pressed into the cooling fin holes. Just like drive shafts I don't like using one that has a lot of balance weights.

Drums & Rotors come balanced from the Factory or Remann shop. Unless they are severely worn they're probably fine.
You can see the round Lead weights on these Al. Drums.
Cast Iron Drums with rectangle weights.

Can drums/rotors be balanced?
i heard from a former midas worker that rotors/drums can't be balanced, but i'm thinking they can.
What is the low-down on this?
P.S. This ties in with the thread that i started entitled "overdrive vs. direct drive+high gear."
