Apparently, I purchased the wrong springs for my car, (Eibach 2085.140) and I installed them on my stock suspension. Going over my first little road bump, the car felt like I hit a hole the size of the grand canyon. Its to the point that I am not driving the car unless I really need to.
I have owned plenty of lowered cars in the past from a slammed (almost scrapping) 98 Acura Integra to a 2007 Infiniti G35 coupe with 20" wheels (also Eibach pro kit with stock shocks) and none of them felt as bad as my current set up.
That said I am looking for Eibach Pro Kit 2091.140 and shocks to compliment them.
I am really interested on the front, since the back doesn't seem bad at all.
TL;DR
Looking for Eibach Pro Kit 2091.140 and front shocks (Koni Yellows or similar)
for a 2007 328XI coupe.
Thanks.
