I had my tires roadforced again lf .017 rf .010 lr.010.rr.003 all well within spec. Tool it to the dealer service manager drove it he felt it and said he wouldn't know where to start.He called ford still waiting on an answer. Drove it to work on the hiway it starts at 58mph you feel it in the steering wheel and accelerator and seat and you can hear it as well. At 80 mph you feel it in the seat and accelerator not the steering wheel, you can push the clutch in and it stay's the same. Turn the wheel side to side no difference. The service manager also said I might have to live with it until it gets worse. I told him i would call ford still waiting. It started this before my new clutch was installed and has gotten worse the super sports helped a little as well as the bmr panhardbar, but it's driving me nuts. Other than the tires and panhardbar the car is stock,the bar was installed to center the rearend.Any ideas?
