I have had my eibach prokit on my 3.5 since 3/02 with no problems. Two weeks ago I had a strange rubbing noise come from my front passenger side tire. The first mechanic said it was the brake pads but the second mechanic I went to said that my car was too low and that I must have hit a pothole or something and nowthat the sound is due to a bent spring. He said the only way to get rid of it is to change suspension back to stock. He said aftermarket springs are not as strong as stock. Eibachs are stronger than OEM I thought. Have any of you had any problems with your Eibach springs or is this mechanic just full of s**t? Any suggestions????? Please help. Thanks.
