On normaly aspirated 996's the X74 sports suspension is
only available for MY 2002 and newer cars which have stiffer chassis compared to MY 1998-2001. Is this going to be the case for X73 as
well?

Related to this, I've heard a claim that from MY 2002 on,
the Turbo chassis rigidity has been increased by 25%.
Any truth to this statement?
