Yes, the stability was improved at 70 or so. However if you
are getting a lot of "floating" at 70 mph then you should check your
caster. Both sides should be the same and somewhere around 4 detrees or
more for high speed stability. If you have bias tires on the rear and
radials on the front, then expect to drive a marble down the road.
In fact it would be real easy to swap ends at unexpected times.
