this is excellent stuff guys.

absentmathis, we should get together sometime. i'd love to get a feel for sport springs. btw, i saw a dead in the water gray e53 getting towed from the middle of Providence Road on Sunday and i was calculating odds in my head....

1) expansion tank/water pump/hose explosion
2) CCV system caught a clot
3) tranny is in limp home mode


back to the topic though. again excellent feedback. i like the 'tiresome' description of the sport springs. were the sport dampers installed as well (presumably YES if this was a factory sport setup from the beginning)?

what kind of eibach springs did you go with? and which struts?

Bilstein B6 = Bilstein HD if i am not mistaken. I've read varying accounts of this setup...both positive and negative results. Perception is everything. I had a pair of Bilstein HD's on another car and LOVED it.

okay, i don't want to beat this to death. i betcha at the end of the day i just go with the stock setup and perhaps upgrade the rear sway and hope to eliminate a tad bit of body roll. anyway, i find that whenever i am driving aggressively enough to make use of upgraded suspension parts in this car, I am also usings BUCKETLOADS of gas. my overall goal with this car is keeping the cost of operation as low as possible and having it last me another 3-4 years (hopefully to 200k, assuming tranny will hold).
