Ford, GM, Chrysler, etc. seldom have their websites updated until the new model year is out. Also , keep in mind, the ordering now is just a catch up for what folks called the " Second Wave" so it is just picking up any remaining allocation for Dealers that was based on 2013 projections.
The main options are all the carbon fiber packages are listed, sidewinders and Corsa tires are listed as seperate options, the color keyed rear is an option, SRT hood for a GTS , new colors ( Silver and GTS-R Blue ), red stripes , etc. The Stryker Red is not a listed color ( wasn't in 2013 either ), these were allocated cars and were manually inputted. They did not get them all finished , so the main focus for this color is to get them all done, and there is some discussion as to whether to continue it into the 2014 for a short run? As many of you know the rumor is it will be replaced with another special color , so that will impact the decision.
