I ordered some UPR pro kit springs and I got them in the mail today. I opened them up and noticed they are silver, unlike the Eibach's which are usually red or black. I realize spring color can vary, however I was a little reluctant to order these in the first place because they were only 209.00 on Ebay. Does anyone have any first hand experience with these springs, or believe that they are in fact identical to the Eibach pro kit springs? The whole UPR thing is throwing me off here...
