Last year, Porsche built a series of race-ready Cayenne S Transsyberia SUVs for use in the rally event bearing the same name. Lessons were learned, and so for the 2008 running of the Transsyberia, Porsche is offering the teams who bought the trucks last year a conversion package that features a number of upgrades. These include a new sump guard, a beefier tire package, tweaked air suspension, a shorter final drive ratio (same as the new Cayenne GTS), plus updates to the transmission programming, dynamic chassis control and traction management systems. Driving from Moscow to Mongolia is no picnic, and these upgrades should make the already-robust Cayenne S Transsyberia even better-suited to handle the rough-and-tumble 4,400-mile course. You can check out the full specs after the jump, and see last year's post on the truck's unveiling for a peek at many of the other modifications that came as part of the standard package.
