I bought mine about 6months ago. I use them with the Tokico shocks/struts. However, Steeda is getting ready to use a new brand called Voigland (spelling) spring. These springs lowered my friends 2002 about 2inches and he needs to get the steeda lowering tie rod. However, since I got my springs 6months ago I didnt need to do anything special, i got lowered about 1 1/2.
