DROPZONE springs suck on our cars...They are remarketed eclipse springs and don't support the V6 well AND they drop well over 3" and sit TOOO LOWWWW ... Yes you will need new struts ...The stockers will never hold up to that big of a drop ....
Hellz yeah. I have dropzone on my car. It sits about 3" lower now. I'm still riding on stock struts

This setup bites my ass every day I drive the F'n thing. spen the money.
I'm going to spend the money for the eibach kit with 1.8 drop from exile. It's worth the price and all the boyz rave about it. Unless you want airide. search the forsales someones selling one for $700.
