i went to test drive an 2000 civic si yesterday. it has goldline springs on it and as far as i know stock struts. also has 17in wheels. as i was driving it, when i would take turns the car would sort of feel like it was understeering though im pretty sure it wasnt. like something in the suspension was shifting as i would take the turns. i wasnt taking the turns super hard or anything either. so what could be the issue here? something actually loose in the suspension or the springs maybe not seated right?

i know this isnt super clear what im talking about, but ill try to explain further if necessary.

thanks for any input you guys can give me
