I just got my set installed about a month ago, and was wondering if the following two things are normal:

(1) Springs (I am assuming) creaking a bit when I get in and out of the car (yeah, I am kind of heavy at ~195lb, but still....)

(2) a very noticeable deep thumping noise when going over bumps or small potholes. (as if my spare tire was loose or something in my trunk - never noticed this with the stock set-up)

Anyone have these same experiences? If not, what problems might these indicate? I don't know much about this stuff, so I have no idea if this is normal.
