Poor Highway Stability
yesterday I was going about 75mph or so and the winds were about 12-14mph. The car felt like it was floating, and not in a good way. My steering felt extremely light (I thought this had nagnasteer?) and it was really uncomfortable, the car felt liek it was all over the place. Now I know you're goign to say "check your struts" but these are new AC Delco struts installed not too long before I bought the car. I mean, it wasn't dangerous or anything, but I just expected better stability and isolation too (lots of wind/road noise). I never noticed it before because I live in a rural area where we don't have expressways and we never usually take my car when we are on them. I like the car, just don't know why it drove like that. (all suspension components have been checked and are good.) I have newer Goodyear Comfortred tires on it, maybe those might be a cause?
