+1

KW also has their basic lowering springs that can be height adjusted as well. (H.A.S.)

 

+1 on the KW V3 over springs. As Lunarx already mentioned, they are fully adjustable on height and ride and you won't get the bounce or sag you get from springs. They are considerably more $$$ but a superior product befitting your $100K+ 911.

Good luck and enjoy!

 

I have KW V3 installed on my 991s, so comfortable and handling improved so much, worth every penny in my book
