Man this fckin VIB drives me insane, I matched all PSI's to spec & still VIB on the highway. How much did it cost to Force.Bal all 4 corners?? This is my next step but didn't know the cost. I complained to service already and they said my wheels weren't bent.. once I force bal & if the problem still exist letting Bmw deal with it. If not LemonLaw.com here I come.
Pls, how much to RdForce all 4 corners?

I am also experiencing a vibration on smooth highway mostly over 80mph on tip-in or constant speed. If I coast in neutral, it is still there, but much less severe. It seems to be driveline related and load sensitive. The vibration feels like a shudder in the body/seats/steering wheel, maybe coming from the rear and it phases in and out. I just bought the car last month and noticed it right away, but has really become more annoying as I drive it more. The previous owner confirmed the issue but did not know the source or seem to have addressed it with dealer. It is a '12 550i with 38k. I have 18" snows on it. I am guessing the 20's will have the same issue. Anyone know the cause and how to fix?

After getting all the PSI's perfect and having front wheels balanced I'm so sick of this non quality ride. No shimmy in the steering wheels, car drives straight, but still has a effff'in shake & watching a bottle of water look like there's a earth quake.

Monday I have a appointment and really going to stress this issue. I'll come back with updates.

I think I remember less than 10#. You should look it up.

Factory wheels? When they have the wheel on the balancer have them check for and show you if the wheel is, in fact, bent.

So I have my service app Monday, I decided to go stock & take off the spacers/tune/etc.. shockingly my ride home from work wasn't bad at all vs (34mile all highway). I think these BMS 15mm spacers are causing almost all of my vibration.
