Having a weird vibration problem at 70mph+, tried taking it up to 95mph and only got worse with speed.
With the car in neutral the vibration is still there, with brakes applied it still there, no weird grinding noises, turning has no effect.
Tried swapping rims/tires with known good; same problem.
Checked that all calipers, tierods, control arms, shocks, etc were all tight.
Drive shaft is new (OEM BMW), all wheel bearings are new (FAG), all suspension components (including all rubber bushings) are less then 2 years old.
Even while holding speed the vibration seems to get slightly better then slightly worse, rinse and repeat; in a rhythmic way.
Very hard to tell if its coming from behind or in front.
Any ideas?
