not everything Pete just a generality.
it's kind of like that out of balance or broken cord tire on your truck that doesn't give you any indication at 45 to around 50 mph but about shakes you off the road at 55 gets a little better at 60 then settles in again at 65-70.
why is it always at 55 mph, or close to 55 mph for about everyone.
not everyone has the problem of course.
