I heard that the Cayman S sway bars are thicker (stiffer) both fore and aft. Does anyone know about this? If so, can the stiffer S bars be installed on a base Cayman? The ride on my Cayman is about as stiff as I want for street use, but the 18" Cayman S tires with the stock sway bars give me a bit more roll than I am happy with. Is this crazy or would an upgrade (if possible) help the handling? I often have a passenger (wifey) and even though the roll in my Cayman is much better than my ex BMW Z4, I am always looking for improvement without harming the overall handling characteristics. I was hoping that someone with a Cayman S who upgraded to some racing sway bars might have keep the old bars around and would be interested in selling them.
