I just received some 4.5" bump stops in the mail. Here's the product:

Now my question is, how do I know where exactly to install them so that they stop my up travel before my shocks bottom out? Obviously, this material will compress a certain amount. Is there a rule of thumb? Should I presume they'll compress 1", 2" etc.?
