Hi, last week I fitted HSD MonoPro coilovers all around to my F20 1 series. After a few miles I'm starting to notice some creaking predominantly from the rear. I believe it's coming from somewhere around the top mount, as it's quite loud on the inside and almost sounds like interior trim (it's not). What causes it is travelling up an incline, ramp or bump at an angle slowly. If anyone has any ideas or has had similar issues in the past it would be great to get some feedback. Thanks!
