i think you are referring to the C55 Performance Package, which is not available in the US, as pictured on the AMG international site. this is an extra package available for only ROW (rest of world) C55's. the c55 in the US is indeed full amg in and out, but other countries can order an AMG performance package, which is an AMG Manufaktur option ontop of the C55 AMG. this includes bigger brakes, carbon-fiber c55 spoiler, pacecar "sl65-style" bumper with side vents, amg lsd, "nurburgring suspension," more alcantara/carbon-fiber inside, racing seats, etc. none of which is yet available from US dealerships as a normal factory option when speccing the US c55 amg. just know that if you buy a C55 in the US, you are indeed getting a full AMG car with the engine, bodypieces, everything, just not to the extra extent of the limited-edition performance package.
