has anyone have a vibration throughout the entire car? I dont really feel it in the steering wheel but i can feel it in the seat and armrest. if im around 75-80 then you can really feel it. below that it seems ok. i made sure to balance my snow tires before putting them on. my car has around 60k on it and im wondering if its time for a suspension refresh. no loose balljoints or wheel bearings. the car does have neuspeed sport springs on the stock shocks. im wondering if theyre tired at this point.
