The G85 Performance package is an option that must be ordered. So far, there are none builft that are available for sale at any dealer that has not been pre ordered as sold. So, if you did not order your SS with the LSD and Recaro seats you do not have an LSD. As the 2006 production model line begins 6/17/2005, it is likely that if you have not ordered and have not recieved an accepted factory build date prior to 6/17/2005, you will not get a 2005 with the LSD.
