PASM front profiled lip

Just thinking out loud here. If the aero on a SPASM-equipped car is tweaked for the slightly more aggressive lip in combination with the lower stance and a higher rear spoiler deployment, will putting the SPASM lip on a non-SPASM car throw things perceptibly out of whack at high speed? Similarly, if one opts for the SD front end - thus losing the active louvers - is rear spoiler deployment programming revised, or does it still act as though it has a standard nose and lip? The engineering and testing that went into 992 aero would have been far from trivial, however to date I've seen no data that show lift and downforce with the various body and suspension configurations. I'm aware that at speeds under under 80 mph/130 kmh the impact of aero is small, but with all 992s capable of velocities in excess of 180 mph/288 kmh, I'd want to know I'm not compromising high-speed stability by swapping out the standard lip for the admittedly sexier-looking SPASM version.

Love the black look 2020.
I expect setting the car up with SPASM rear spoiler settings would take a few minutes at a dealer or a shop with PIWIS. The question is whether they would do it if the lip is present but the car isn't running on the lowered SPASM suspension. The last time I asked the dealer if they would make a coding change to turn off TPMS (which was relatively easy to do with a Durametric) the answer was an unequivocal no; they wouldn't do anything that could potentially come back on them with a liability claim in the event of an incident or accident.

Would the change put you at certain grave risk? No, but if the driver got themselves killed at speed and a family was looking for answers, it's a potential liability that a dealership doesn't need. So, if you want to engage in hackery, you'll need to find a good tuner who can make the changes.

^ @detansinn is right. Its not cosmetic and there is a science behind it. Anything you do up front you need to balance at the back. If your set on the front change, maybe look to add a diffuser at the rear, to help facilitate airflow out the back. Make the rear spoilers job a little easier.
Just thinking aloud.
P.S. That's one fine looking machine there.

While yes, there is a scientific difference, Im not sure this would be of much concern dynamically unless we're talking 170 mph plus...and even then with the wing deployed, eh would likely all be fine. its another thing if there was a considerable shelf being created on the sides and some canards, but that front lip alone...wouldn't concern me.
