Mercedes Benz SL63 AMG powered to 600 HP CK63 RS by Carlsson

Not happy with only 518 hp and a 4.5-second 0-to-60-mph time from your shiny new Mercedes-Benz SL63 AMG?

Lucky for you, the German tuners from Carlsson are now offering performance-upgrade kits in the United States.

Through GGI European Tuning in Miami--the exclusive North American importer of Carlsson parts--SL63 owners can massage their rides to churn out 600 hp and 520 lb-ft of torque and to handle better than stock. With the changes, Carlsson renames the vehicle the CK63 RS.
