Hi all, I have a 2017 Giulia base. When I am on a smooth surface the car drives incredibly well. However, when hit an uneven surface I start hearing something moving under the car. I guess the best description is a clunking noise. It stops when idle and only begins again when I hit an uneven...

I had my car on a lift today and it was the first time I actually got to see under my car and I was wondering why they cover/shield most of the underside, and in some cases even have aero bits, but not the area I circled in blue? Does anyone know?
