A lot of the major tuning companies seem to want to drop the air suspension Cayenne S/TT 40mm. Is this safe for the suspension geometry? Has anyone done this? How is the ride compared to the stock low setting? Does it automatically lower ride height when you hit higher highway speeds? Of course I'm talking about street driving. Why didn't Porsche just include this 40mm lowered height option to begin with as a highway high speed mode?
