I want to know if anyone out there has an answer for my question regards to sport suspension fitting on non sport e60. I have an 2004 525i and is looking to purchase sport suspension off an fourm member. I would like to know if anyone with experience or expertiest can help me on answering my question. The springs and shock i'm getting off an member on the fourm is an 2007 530i and I want to see if it will fit on my 2004 525i before i commit to purchasing the suspension. Any advice is much appreciated.
