your eibachs, are they the sportline or the prokit?
the sportlines lower your car more so then the prokit. My friends on the prokit and his oem shocks actually have been holding up. Meanwhile... I was on the sportline and my oem shocks bottomed out after 1 month. I bought stiffer shocks (koni yellows) and a camber kit (skunk2). It's a very good idea to just get everything at once so that you don't speend $$ on aligning each time.
