actually, i bought mine on ebay and it stated that #2552.140 is for crossfire (roadster or coupe). i had the springs installed at a local performance shop wondering about the whole 20mm thing (i didn't hear a word about) - anyway, it came back looking pretty good. i chose the eibach because it seems like it has the least drop of the other springs (driving has to be at least somewhat practical - it is my daily driver, after all.) after the shop did the alignment, they told me that the rear needs camber bolts (which don't exist, apparently) - be prepared. chrysler only sells camber repair kits ($850). there have been some threads about the whole negative camber issue, but it doesn't seem to have really affected the tires wearing all that much. so, i'll live with it and flip the rear tires at the end of the year if it looks like it needs it. the drive is great and seems a lot stiffer.
