I think most of us have the Eiback springs, H&R spacers (10mm front and 12mm rear, dont forget the correct longer lug bolts), and i also have speedybenz adjustable camber arms for the rear.

Some of us have also changed their shocks out (Konis i believe?), but i havent done this.

If you search for any of those key terms, there are plenty of threads with installation info, pics, and where to buy.
