I want to lower my A4 ,what will I need and how much will it cost?
 

Ive looked around, but couldnt really find anything.. I dont want to lower it much, probably less than 2.5". So all i need is springs right?

yes they have springs to drop 2" for our cars and you can fit them on stock struts but they won't last as long or perform as well as if they were on aftermarket struts. you should go lower though
