No obvious movement using hand only, but I don't trust that. Brembos, ZHP arms, Lemforder bushings, OEM pads. Wheel hubs have been cleaned througly before putting new rotors on.

However, I am running with one less wheel nut on the driver's side. Apparently some incompetent mechanic was able to strip the threads. Not sure if this would cause a vibration though.
Next time I'm under the car for suspension work, it will be for new struts/mounts and tie-rods. The vibration doesn't bother me that much to do the suspension work in the near future.

It is not strange to get tires balanced, yet they are still out of balance. Can you swap the rears with the fronts? Staggered for you?
Find out how to check strut mounts and check them too. Gotta start eliminating things. (how do you check strut mounts on the car? disconnect the lower end and try to wiggle?)
Square setup 225/45/17's all around. Already rotated rears and fronts. No difference.
As far as I'm concerned, the correct way to check the strut mounts is when they are out of the car. I guess, they'll have to wait.
