PASM sport Lip+Wing
it's been shown that you can purchase the front lower lip from porsche for $179 (not bad at all, especially since this piece will get damaged easily)
but the PASM sport vehicles also have programming for the rear wing to deploy slightly further to add additional downforce on the rear.... does anyone know if its possible in the PWIS system to add this function to the computer if/when you add the PASM sport front lower lip?

I think the point is that Porsche have decided that with SPASM (-20mm) the aerodynamics have changed and thus it is necessary to amend the front lip and the rear wing angle to ensure the right level of downforce and thus front / rear stability at speed.
Costmetic (improvment) issues aside I think if you start messing with adding the lip and wing angle to a PASM (-10mm) car you will probably end up upsetting the aerodynamics and thus making your car less stable at high speeds. Sounds dangerous to me - wouldnt it just be simpler to order / find a used SPASM in the first place??

i did not order SPASM because you are then forced to get 20" wheels, and PTV... ergo 6k for -30mm and options i did not want... versus 300$ springs, $200 lip, and $xxx for Pwis adjustment in computer..

Riley I don't have any information about a different rear deployment angle depending on the suspension. I only verified that in the cars with a sliding roof, it extends to two different positions depending on whether the sliding roof is open or closed.
Interesting that the 991 is the first Carrera to achieve downforce on the rear axle but only when combined with the optional PASM sports chassis. Obviously, its lift coefficients have been significantly reduced by the new design and function of the rear spoiler and by the detail modifications to the front side and the improved underbody panels.

The configurator is a bit vague on the amount of extra:ness:
PASM Sport Suspension
Electronically controlled damper system with two manually selectable settings (standard and sport). Includes a reduced ride height of 0.39 inches (10 mm) from the standard Carrera S suspension.
Also includes an aerodynamically adapted front spoiler lip and further extension of the automatically deploying rear spoiler for futher lift reduction.
