Excellence Magazine June 2016 "Top Gun Turbo" (review of the 991.2 TT & TTS) pp 58 excerpt:
↓↓↓↓ FWIW.....not sure why the axle lift makes any difference?
"At speed, it was quickly apparent that the handling & poise of the new Turbo have been
ratcheted up a notch from the already impressive outgoing model. Ulrich Morbitzer,
Director of Chassis Engineering for the 911, explained that while the
SUSPENSION HARDWARE IS UNCHANGED, several of the settings have been re-calibrated,
particularly the PASM damping whose performance envelope has been extended at both ends
of it's operating spectrum."

All the suspension part numbers match the .2 Carrera which can be optioned with SPASM.... except for the shock absorbers. Is a retrofit possible?
See attachment with parts high lighted for reference....

Good question. I like the stance the optioned non-turbo 911 have (well they are all turbo'd now, but you know what I mean. The aftermarket springs are all too low for me although they do look good in pictures. I would be happy with a 10-12mm drop. Especially living in the Northeast.

When the Porsche axle lift system is engaged, air is pumped into the reservoir at the base of the shock housing and an internal piston moves upward bringing the rest of the suspension (and car) with it. When the axle lift is not in use that piston sits at rest on the base of the housing. By installing traditional lowering springs you are also attempting to lower that internal piston, which is not possible given it is already sitting on the bottom. Now in the chance that the spring and piston are somehow not directly correlated, it could possibly still rise enough to unseat the shorter spring (which among other issues, automatically makes it ineligible for TUV approval).
When the need to get lower has arisen we have used a system made by KW. However, it represents a much larger cost than just lowering springs.
Hope that helps.

This was Techart's reply... Their springs are compatible..
according to our engineers you can use the sport springs in combination with the Porsche Lift System (option 474).
With TECHART springs you get the clearance lowering by 20-25mm. Accordingly the Porsche Lift System reduces its front axle lifting by 20-25mm, from the originally claimed 40mm.
