Hey guys I installed Eibach lowering springs on my car a few months ago and the front ones (the back springs are great) creak very loudly and can actually be felt from the drivers seat after hitting a speed bump etc... Did I screw something up during the install, or is this a common problem with a simple fix? Please help, any info appreciated. Thanks.

Well I'd hate so say it but it sounds like you just made an error with linging the spring up on the strut. Did you notice that the strut had a little indent where the spring should sit? Perhaps you did not set the last coil of the spring in the indent and everytime you are compressing the spring it is trying to sprial downwards, following the struts design, so it will settle itself into its correct position. You could just wait it out and see if after a while the spring does situate itself but i would take a look at it and see if that is a problem and to make sure that i didnt put the spring on upside down! haha. Good luck and if you have any more questions let me know.
