there are many good springs out there. eibach prokits, eibach sportlines, progress, H&R OE, H&R race, goldline, and many more. prokits give the least amount of drop as to where sportlines, H & R race, and progress give the most. you need to replace your stock struts with some that allow more suspension travel when you lower your car, otherwise they will blow out in 10000 miles or less.
