I gotta' chime in here fellas;  I've been driving cars for a lot of =
years and learned that a harmonic vibration most likely is NOT a wheel =
imbalance. =20
 I'd lean towards CV joint or engine imbalance (I've had both of these =
situations result in harmonics)

  try getting a mounted balance--the wheels are balanced on the car, so =
it=20
  essentially balances all that rotating mass (rotors, hubs, etc). my =
shop=20
  does it for $8 wheel. i had the wheels/tires balanced unmounted first, =
then=20
  mounted; i was amazed how much tweaking needed to be done with the =
mounted=20
  balance.  the car is lowered, and is rock solid as fast as i care to =
go...
