BMW: BMY 740i front end vibration, control arm bushings, warped rotors

Question
I have a 97 740i.  The front end vibrates at 45-55 when slowing down and there is minor vibration when getting up through these speeds.  I had all brakes discs and pads replaced and tires just balanced.  Can this be control arm bushings or warped rotors?

Thx/David

Answer
David,
 I doubt this is warped rotors, as you should only feel it during breaking.  Chances are that some connection in your suspension is worn.  It could be control arm bushings, but it could also be the steering setup.  Check for play in your suspension.
