What would be the best upgrade for an e39 528i. There are quite a few combos out there. I just want to stiffen it up and lower it a bit. Nothing too serious. It's a driver not a track car. Bilstein with H&R sport prob the best? or are Eibach's good too. I see a lot of Votland springs comboed up with Gabriel and Bilstein on ebay but all the rest seem to drop less in the rear end but Votlands are the same all around. Any reason for that or are Votlands crap?
