Few little updates.
First, I extended my rear wheel skirts down a little bit farther. I also tweaked the rear of the kammback a little bit. I lowered the mid section by 1", and the rear by 1.25".
Then I did a little bit of work under the car, extended the rear section of the bellypan and incorporated a diffuser.
Then I decided that the car needs a little branding, so here is my updated upper grill block (In hindsight, maybe I shouldn't have used a clear coat, bit too shiny).
