My ST bars are still in the mail, DsR, so I can't say. I know that the Base Prelude front bar is about 22-23mm(?) and that the SH front sway bar is just a little bit thicker. The ST front bar, if I remember correctly, is basically the same as the factory SH front bar. The ST rear bar is 25mm and is at least a 2-3mm jump over stock. I need to get my numbers straight here.
The main difference between the factory and ST bars is that the ST's are solid all the way through, whereas the Honda parts are slightly hollow. I still haven't decided if I want both ST's installed or just the rear. I can tell you that I do not go to track events, so these mods are purely for the street and highways.
Don't you drive an ITR, though?
Edit: Just saw your sig

Unless they are of absolutley horrible design.. the Tanabes are going to be fine.
btw do you know the thickness of the front ST?? I picked up a rear ST for my Lude, but I think Ill stick w/the stock front to promote rotation.
