Hmm. I was thinking it was the splitter and flat bottom of the undertray smoothed out the airflow under the car, creating a lower pressure, and air flow through to the radiators, and the high pressure in front of them created the down force (high pressure tries to move to low pressure to equalise- or something like that).
I never contemplated the idea that the 'flat' part of the bumper would create a big high pressure, and splitter gives the high pressure something to act on. Makes sense now I have read it.
Might be worth taking a second piece of ply to extend the front splitter and see what effect that has next time I hit the track. I want to move to Goulburn
I went and had another look at the car tonight. I can exert a fair bit of pressure on the splitter with a foot, but don't think it would support my weight.
Anyone have any idea how much downforce something like a 50mm splitter can generate?
