I think I know what that is for, but I am not really sure. All I know is that I am laughing my butt off!!

I am sure that there is no pune intended toward anyone.
As far as settling... It will take some time and that time is dependent on how much you drive and what sort of conditions you drive in. the roads where I live are pretty rough in some places and mine settle very well in about a week. I think it was about 500 miles. Since I have installed my Roush/ST200's, which was almost a month ago, my car has settled quite a bit. Not slammed mine you, but nice and even. The ride is very smooth as well, yet tight and very stiff in the tight corners.
I think you will be happy happy!!
I have some pictures of mine
