X5Girl, you have the right idea. In the Porsche world, with aftermarket sways, adjustable droplinks are used to eliminate pre-load on the sways. It just doesn't make sense to have too much preload.
I made this thread awhile back:

I had mine custom made from a company that makes parts for Porsches. I'll be using their toe links and drop links for my 996 once I have time this summer.
I wouldn't expect much from American drivers/owners though. It seems it's more about bling than actual functionality.
BTW, it looks like the Phoenix drop links are just modified OEM ones with the standard OEM ball end. The droplinks from Tarrett Engineering are fully custom with rod-ends. Here's the website from the company who made mine:
