If you haven't reviewed some of the ongoing threads about suspension lately, it's worth doing.
Exec Summary: The Porsche spec ROW ride height appears noticeably higher than most people think is "Euro" ride height. Many slam the car down to 4 " above the pavement, thinking it looks and handles better that way. It doesn't handle better like that because it changes the suspension geometry substantially and unfavorably, especially at the McPherson strut front. Do not go by fender arch height, because that will be different for different combos of tires and wheels. Note that you have 17" wheels and tires.
Therefore, check the actual measurements "a to b" that Porsche specifies. It looks difficult, but it isn't, especially after you have done it a coupe times. If you go below those specs, understand that it will adversely affect suspension compliance and bump steer, unless you have the spindles raised on the front struts. At the rear, lowering the suspension will increase harshness, unless you install something like the 935 suspension parts.
If you aren't going racing, that a lot of money and effort just for appearances.
