In an effort to outfit my little E30 with some high quality goodies, I am wanting to keep expenses low. Is it conceivable for me to install a set of springs and shocks - rear shock mounts too - at home with a simple set of hand tools? I am looking at the Bavarian Auto kit - Eibach springs and Bilstien shocks and their solid upper rear shock mounts. Any input? Words of Wisdom? Warning?
