Rear diffusor and front splitter inspiration

I more or less gave up on my CFD simulations. At least for a while. I could not get consistent results and the obstacles were just too many to keep me carry on. But before I gave up I did some simulations with an engine bay under tray and a rear diffusor, and according to the simulations it did quite a big difference on both drag and downforce.

Today I received some inspirational pictures from Paul Cardy on his previous CSR. I think I'll try to do something in the same lines.











Paul writes:
"The diffuser was attached to the chassis using these brackets with threaded inserts as per picture 1, the rear end of the diffuser was held using these hanger brackets in picture 2, and the main body was held in position using P type clips with steel surrounded by a rubber sleeve and clamped round the chassis tubes. 
The diffuser was made by Freestyle in fiberglass and I had him glass in some carbon on the last section for the look. I made up the front mounts and cut up the diffusers to fit as this was the first ever to be fitted to a CSR so its was a make it up as you went along. 
The front splitter is a sheet of carbon cut to shape its fixed to the chassis with the P clips again. The front upright section is aluminium folded and cut to follow the underside of the nose cone and fixed to the splitter its wrapped in black vinyl."

I also would like to cover the engine bay. But before I do that I must take care of the already high intake air temperatures. But that is a different subject.
