I have not seen too many cases of having to make geometry changes. Most likely you will have to soften your suspension dampning. The carcass on Bridgestones are more stiff than other brands.Originally Posted by yakuza
Being stiffer when you hit a bump more of that energy is passed on to the suspension. Compared to a tire with a softer carcass that will absorb more of that energy. Hope this explains it for you. Feel free to ask any other ??? you may have.
