Hi,
They were posted on here somewhere. I couldn't find them when I looked.
Here is a copy of a post re the Bilstein rates, which are streetable although stiff. I don't know if the stock shocks can handle them:
"The Bilstein kit is 275/230, which nets out to somewhere in the 2.0/2.5 hz ride frequency range. So that's in the ballpark."

P.S. Found it but I can't copy and paste. Look in the "Problems with my FK lowering springs" post.
