Do you have some form of CFD To create the shapes and test ?

Thanks Martin, but i still prefer something a little flexible for splitters and front undertrays.

Unfortunately not Scott.

I have test result though..

numbers are in newtons. (1N = 0.22lbs).

Red arrows represent lift/downforce at air flow of 144km/h
Blue arrows represent lift/downforce at air flow of 200km/h

It shows that the front end of the Scooby gets lighter with speed. The front splitter I have put on will have helped that a bit but some more work on this element would help balance it out with the rear that actually has a good amount of downforce. The downforce is probably not soley down to the rear spoiler but a combination of the rear spoiler, roof spoiler, rear diffuser and flatter floor sectioning.

The front splitter / undertray material has been heat tested and hammer tested and passed both test very well

The 3mm Aluminium Composite Sheet Comprises of a Polyethylene Core Sandwiched Between 2 x 0.3mm Aluminium Sheets. It is very light and blumming strong.

I have costed it out and for the full front undertray it is

Nice one Dunc.

Sounds like things are moving forward nicely.
