Paul,
Agree completely. It seemed that the car was fine until
driven, not a time factor. Maybe I misunderstood his description, or
maybe "sponginess" is a little vague.
I'm just sensitive to this as we spent time bleeding the
brakes on the race car only to find the closest wheel's bearings had given up.
