DIY rear drop links
Because it's only 19F outside, and my PS2s have become hard as rock in the cold, I figured it is a good time to do a few DIYs before I swap to winter tires.
For those interested in swapping the OEM drop links, it is a very easy task that took about 20 minutes total time.
First...things you'll need:
Only in Wisconsin-ites...
Place your car on ramps, lifts, or stands:
Tools needed: an open ended 16mm, 17mm wrench...ratchet wrench for those who are lazy ... the T30 Torx is needed because the OEM drop link needs counter rotation to remove the bolt.
As you can see:
Counter rotation will prevent the threaded part of the drop link from spinning freely:
After removing the lower bolt, move to the top bolt:
Adjust the length of the adjustable replacement drop link and reattach...many drop links have varying adapters to position the body of the link parallel with the damper. Ideally, you want something in a similar parallel configuration.
Final product:
As for tightening torque, Porsche does not specific exact torque specifications in their PIWIS technical workshop interface...they simply report that the bolts should be nylon insert locking nuts, which need to be replaced, rather than reused.
Have fun!

On an adjustable bar, as you move holes you change the angle of the drop link. Ideally, it should always but straight up and down. Changing the length will allow for some adjustability.
Second and more importantly, when a car is corner balanced with an adjustable ride height, each corner will most likely have a different right height. If your left rear shock is different height than you right and the drop links are the same length on either side you have a pre loaded sway bar that would give equal resistance in left and right turns. The adjustable length links allow you to dial out this preload.
