Sway bar stiffness

Does anyone know the various specs on sway bars? I looked in the road race section and if it is there could ot find them for a C4. I am looking for bar ratings or at least relative stiffness that is not obvious. The wall thickness of the hollow bars would be real useful.

Thanks for the leads. I am doing a street car just trying to get some of the rool out. The 32 mm is just way too much and has way too many install isssues to suit me. I changed to a 26 solid rear from a 24 and just enough to help the feel of the car and had a 32 I bought quite a while ago on some reccomendations. The fitment was poor in my mind without changing a bunch of other things and in general much stiffer than I had in mind. From what I have read my only fall back position is either a 28mm solid or 30mm tubular. Is the gM 300mm as stiff as listed or possibly thinner wall bar so softer?

I went through all the leads and ran across a spring and sway bar chart on another site. It looks like the 26T front and 26 S rear combination was used on a bunch of years and models with varying spring rates. I am wondering if the stock 26T bar back in front with either poly bushings or heim joints on the front will get me where I want to be. I am thinking the most I want is the 30mm T sold by Addco is the part I need in the end. That was a very cool trick with the front end shims to get the clearance on the bar wherever you want it!
