Boxster S suspension in a Base

[Kenny Boxster]

Believe it or not, base struts and S struts are the exact same part. I confirmed it when I changed my suspension. As far as comfortable ride, I feel Bilstien would get you closest to your goal considering they are the OEM manufacturer of Porsche struts.

Trivia:

An Audi/VW model may have boxster struts as well. I saw the logo and it doesn't surprise me, but does anyone know what car shares the same part? Looked up the ref number but couldn't find it.
