Splitter angle?

You are trying to create a vacuum or negative pressure under the car. When there is a negative pressure air travels faster creating lower pressure hence more down-force or negative pressure. That is why a real diffuser tries to straighten the air and make it exit faster. That is why you want a flat as possible bottom on a car or even fully plate it. It creates less turbulence for faster exit. Just think weather if your are in a low pressure zone it tends to be windy as air travels in to fill the gap.

With my setup I can adjust the rake on the splitter. I try to get 2 to 3 degrees down. I measure this with a digital level at the track with the car sitting as level as I can get it.

I think as long as it is level, or slightly lower in the front, it is effective. Usually you add venturis to the undertray instead of cambering the entire splitter.

If I remember correctly, the RX8 had spun off track right, and thought he was in the clear when he pulled back on track. The DP car came around that turn pretty quickly and had a windshield of RX8 and took evasive action.

That rx8 driver was really bad. First he spins for no reason, then he pulls 90 degrees across the track with multiple cars flying towards him. He must have a lot of cash, because he didn't get there on talent alone...

I just measured my undertray and the angle is 3*.
