Its my car. I noticed that when I installed the rear bolt on diffuser that the middle section hangs pretty low. I did install the brackets and I tried to pull it up as much as possible. I may cut it off a bit but just haven't had time.
The diffuser middle section seems to hang as low as the full bumper as seen on Kevins white car in the pics. I just kept thinking that this is normal. Let me know if its not. I bought the diffuser from CZP when I was there for Zcon. Seemed like a high quality part and installation was easy after I silicon as my rear bumper is wavy. Oh and getting my B&B to fit took about 8 hrs.
