I going to add that upgrading the rotors and pads might not be a bad idea before I noticed this fact. Probably not necessary

If that doesn't help, take it to a brake pro - they can turn/replace them if needed.
The only reason I wouldn't bother with that is because he mentioned it happens at any speed. I had success with that method when the vibration only happens during high speed braking. My wife appears to be pretty hard on the brakes because this issue popped up around 12K miles on our Z. When I started DD the Z around 20K miles it was happening when braking from 20 mph or faster. I tried re-bedding the brakes with zero success (I might have had more success if I had done it when the issue first appeared). I ended up just replacing the front rotors and pads because I wanted slotted rotors, but turning the rotors was most definitely an option.
