Default install a CR Wing with or without AP1 lip?

Visually my s2000 needs a wing. After driving 100+ mph, it also needs a wing. The car's traction just gets too light at high speeds.

Searching the forms I've read some discussions of the CR lip with no wing & that the AP1 lip is aesthetic only and really has no aero benefit. I've read https://robrobinette.com/S2000Aerodynamics.htm a few times. What stands out to me from the reading is:
The S2000 has a tendency to understeer on fast corners at full throttle when running a wing. Adding a splitter to the front bumper is a great way to help restore some high speed aero balance. To get the full benefit of a splitter it needs to be at a low 3 inches or less above the ground so that air flowing below the splitter will create downforce but at that height very stiff springs are required to keep it from hitting the ground under heavy braking when the nose pitches down. But even at stock ride height a splitter will be beneficial because the high pressure on top of the splitter will create downforce.

It is possible to tune the low speed and high speed handling separately by adjusting the car's aerodynamics for high speed handling. You can use the normal suspension tuning (alignment, sway bars, shock settings) to make the car oversteer on slow corners to help you rotate the car, but run extra rear downforce so it under steers slightly at high speed
What I cannot find a lot of information on is what the CR wing will do the AP1 lip. The reading I linked has a description of what the CR wing will do with no lip. I need to know a little more before I spend $1000+ on an OEM AP1 lip or $800 on a carbon fiber AP1 replica lip. End goal would be LOOKs &
tune the low speed and high speed handling separately by adjusting the car's aerodynamics for high speed handling. Make the car oversteer on slow corners to help you rotate the car, but run extra rear downforce so it under steers slightly at high speed
& has some extra traction/stability at high speeds.

CR wing was designed to work with the CR front lip.

Did you ever get good tires for this car? Where are you driving 100mph?

The wing and splitter combo you choose are dictated by the aero balance you want.

Meaning...if your question is just "how to make my car feel stable at 100mph+ using aero"?

"Idk...how do you?" is the actual answer to your question.

Your aero needs to work with itself. And the suspension, tires, alignment, etc.

Yes, Isolating to aero, buying a matched set (CR aero in this case) is the easiest thing to do.

But what about the CR suspension
and tires
and alignment
and geometry

?

OP, I re-read your post to try and figure out what it is you want.

It makes no sense, and there's no real answer.

Adding rear downforce will stabilize the rear of the car. A wing will add (x) amount of downforce at (x) wind speed. More rear downforce typically means more grip from the back.

More front downforce means more grip from the front.

Aero tuning takes...well...tuning. Data collection, lap times, etc.

You're asking how to...??? make your car ??? do what at 100 mph?

wth are you asking, bruv?

Buy CR aero for a nice easy place to start.

Thank you. I’m learning.

U can run a diy splitter or an ap1 splitter. Search the web. There are pics of some custom splitters which are not that hard to duplicate.
