I just bought these off someone and after puting them on my car i fiured out that they were for an LS1 car, since they lowered my car too much. I'm looking to get $50 plus your stock front struts/springs and rear springs, Or I'll trade even for a set of 98-02 eibach prokits.....or 93-97 sportlines or prokits. I have pictures of how my car sits with them if you're interested....
The part #s for the springs are.
Sportline 4.703
They lower ls1 cars 1.6" in the front and 1.4" in the rear.
and lt1 cars a lot lower than that
