I recently had Bilstein performance front struts placed on my 1990 780 Bertone 4 cyl turbo which elevated my front end an entire inch higher than the back end. The coil springs actually creak and rub somehow when the car is driven. My mechanic assured me that the struts and springs are seated properly and he thinks that the struts are so stiff that theire responsible for elevating the front end. IPD guys said that would be really unusual and almost unheard of (at most only 1/4" would be expected). Has anyone experienced this with the Bilsteins or have any recommendations? Thank you. Sergio
