Cutting Weight
This is one of the places the new IS has seen some of the biggest changes. Lexus has spent a lot of effort to cut weight where they can, while also stiffening up the chassis. It really seems like they spent a lot of time on the little details too, as E46CT was quick to note.
Also one tid bit I think some may have missed: Lexus has switched to wheel bolts for the new IS now. BMW style. For extra rigidity and handling!
Member Sansuke took it a step farther and just posted a capture of the details straight from the press release that covered the much lighter suspension components.
