Can someone post a pic of the said mount? How much does the mount stiffen the FSB by?
I have been using adjustable FSB mounts from Cusco but they only stiffen the FSB by 16%. Not enough to really make a noticable difference in roll angle IMO (though I feel they do help in transitions).
I would argue those mounts are not Street class legal. Only bar allowances are allowed.
The way they work is changing the motion ratio of the swaybar to Control arm attach. Doesn't change bar rate, but wheel rate is what matters and M.R. is significantly important in that calculation.
IMO adjustable mounting brackets squarely fit within the rules as 'supporting hardware' to a sway bar. (Heck, the rule directly states that brackets are permitted).
Given that SCCA allows performance improvements from other 'supporting hardwares' (namely, stiffer bushings and adjustable endlinks) I don't see why this would be an exception, but I guess there may be different interpretations.

I agree
CIRO's ladder mounts are pretty trick, I'll try and post up some product info for you in a bit.
The Ciro ones are the same concept as the Cusco, just with a little added range of adjustability. I've had them for 2-3 years now, but I don't know if Rick ever started selling them publicly.
According to Cusco, the outermost mounting hole (what would have been the stiffest setting) is not to be used. I have wanted to ask them why but never got around to it and have been just using the third hole.
The only reason for that is because it's designed with the stock endlinks in mind, so they can't reach without being subjected to a whole lot of stress. At least that's what I can remember. If you use aftermarket endlinks there shouldn't be a problem.
