Beware the slippery slope......

Hi PWICK,
It has been said that the factory set the rear spring plates for Increasing the rear height to compensate for rear settling. This means that you may not have any adjustment available to lower the car unless the rear suspension has been worked on AND someone indexed the rear bars so that the adjusters were set at “mid point” AND that the PO had the car corner balanced and aligned AND there is some adjustment left to lower the car. Short answer, probably not without reindexing the bars.
Do you know if the suspension bushings have been replaced??? If not, it is probably time to do them. In the process of replacing the rubber, you have the choice of original stiffness, or sport stiffness, (assuming mostly street use, which rules out poly bronze, polyurethane, or monoballs).
Additionally, you are likely to find some abrasion of the front T bars, due to wear/sagging, which leads to the previously cited recommendation to increase the size of the T bars.

Importantly, most suspension work will require re-establishment of ride height and realignment, which has a significant cost that if you plan thing out well, you only have to do once.

This suggests that you talk to an experienced pro that has, or can recommend a balanced package to hit your goals. I don’t have much Porsche suspension experience, but have been well served by Chuck At Elephant, both in understanding my desires and recommending suitable components, followed by good service.

Moving on - way down the slippery slope,, while you are in there:
Ball joints, blast and powder coat the parts, or plate them,
Steering rack overhaul, mastercylinder, wheel bearings, caliper overhaul, discs, pads,
Spring plates with more/easier adjustability, adjustable anti-roll bars to tune the handling.

The list is dependent on “need” and desires, then do the corner balance and align.

Hope you don’t find any serious ancillary issues/RUST.

Good luck,
chris
