You decode Eibach's part numbers like this:
0900 (length) 225 (diameter 2.25") 0900 (Lbs. per square inch to compress)
Yours are 9" x 2.25 x 800 lbs. If they were for the front they should be 0900.250.800 unless Ground Control has changed everything.
A couple of pics of my Eibach rear springs. The 0600.225.0900 are what came with my GC kit. The fronts are 0800.250.1200. The box picture is what's in my car as we speak.
