I received the rear springs couple weeks ago, just been too cold and tooo much snow to get to my other garage.

Got another question..is there any downfall or any reason a shop would not install different springs on the struts if I have them replace with new struts? I done it myself on my other hhr but don't know if I feel like doing it this time. The drop wont be as much since im going with the stock cobalt springs. Even with the goldlines full drop I did not end up using the alignment bolts I purchased, but still have them in case.
