Glad this thread opened back up. To put it simply, just because something works for one car, doesn't mean it will automatically work for another. But there are some easier basics that hold true in just about every case.

The easy thing would be to lower the car as long as you don't get into destroying suspension geometry. Thats a whole nother issue. But lowering just the splitter would be the next option. You will need some sort of air dam to fill the space between the bumper cover and the now lower splitter tho.Got it. Thank you AJ
Yes ford declares 24lbs DF at 80mph
So lower even more the car or the splitter should be my #1 thing.
#2 better strong material
Thanks AJ

The splitter is not going up. The throat, or inlet of the splitter is going up, but the exit area has a larger volume then the inlet usually. This is for 2 reasons but both take advantage of Bernoulis principal. It squeezes more air under the splitter, which forces the air to speed up. When air speeds up, you get a dynamic pressure drop across a surface. So you can get more downforce with a raised splitter throat like that. Keep in mind this air needs to go somewehre. So there has to be some sort of tunnels in that splitter and/or is channeling more air to the diffusor. This will allow the diffusor to work better. We can assume the car pictured probably has a higher rear weight bias so more Df is needed in the rear then the front. Its also only a GTD car and they are limited on what they can do aero wise.I know nothing about aero, as can be seen by my bone stock car. My question is how does the following splitter help? It seems to be fairly common now, the splitter going up not down.

ehhhh to an extent but not always. It could easily get to the point of to much, but the trend in the past few years has been seeing them get bigger and bigger.So AJ
BIGGER INLET increases OVERALL DF
If there are not tunnels to exit air innthe front.
With tunnels DF is more focus anteriorly?

All good points I may have missed. Yes, the Ferrari has a complete package around the size of the throat of the splitter. As you mentioned, most of us, myself included, would probably not benefit with that agressive of a splitter inlet. And you hit on a good point. The "brick" face of the average mustang would probably build up a larger high pressure zone in front of the car and get more "spillage" of that high pressure to under the splitter, where as a very small nose of a Ferrari wouldn't get that effect as much, so making the splitter throat much larger is a trick to get more mass flow under the splitter.I get that forcing more air under the splitter will increase the speed of the air and make any tunnels or ducts on the bottom side of the splitter more effective. For race cars with intricate splitters and flat bottoms, this makes sense. For the weekenders among us (like me) with flat splitters and no clean air under the car after the splitter, does it make more sense to take advantage of the "racing brick" aspect of the front of our Mustangs creating high pressure on the top of the splitter that extends in front of the bumper? It would appear the mid-engine Ferrari in the picture has much lower frontal area than our cars, and it can take advantage of the air that is forced under the car.
It's simple, if you have an S197 you use the IMSA splitter and wing for some aero downforce, if you want more you use the PWC splitter and wing, if you want to go beyond that, call AJ Hartman
Nah, S550. I know nothing about this stuff, just generalities. I probably should have just shut up and read. I couldn't help but wonder about the FRONT EDGE of the splitter going up and what that did. I'm purely a mechanical grip guy, but would like to know more about aero, especially front downforce because that's where this car needs help IMHO. I think better venting in the hood, or a totally new vented hood is a good start since it also could stand some more cooling, also just MHO.
