Hmmmmmmm, lowered on Eibachs? I wonder if your tyres are rubbing like mine were?? My car needed the suspension raising about 15mm after fitting these..and it actually took me a day to realise that that was what the horrible noise was
One other thing, I loosened off my top nuts on my rear struts, rolled the car onto level ground and then did them back up again in an attempt to get them to settle right. Didn't need to as it happens but still would try it if I had unexplained noise 'cos the fitting of these does move stuff around a bit... just my thoughts..
