I just finished installing the front springs on my Whippet street rod and they chatter quite loudly when the suspension goes up and down. The insulators are in place at the top of the springs. Looking at the picture attached, are they in the correct position? Also, they compress about 1 1/4 inch. Is this enough, or are these springs too stiff for my ride? I don't know what the rate is on them, nor have I weighed my car yet.
