German aftermarket company, Vath, is no stranger to building some of the most desirable Mercedes programs in the market. The company has a portfolio of these models, including programs for the A-Class, the C63 AMG and the SLS AMG, among others.
Not one to be content with just fitting useless components on the SL63 AMG, Vath opted to use parts that would improve the sports car’s aerodynamic capabilities, beginning with a carbon front spoiler, a new rear diffuser with fins and a large underbody, and a rear lip that was also made from high-class carbon. Rounding out the exterior mods is a set of 20-inch, three-part forged rims with titanium-colored spokes to go with a high-performance brake system that features a 390 mm (15.35-inch) brake discs at the front axle with six-piston brake calipers, as well as Castrol SRF racing brake fluid and brake line kit.
The interior of the SL63 AMG was treated to a fancy carbon-black finish, all of which was exclusively handmade in Germany. Among the components finished in carbon black include the middle console, the front ashtray cover and two-part door stripes. From there, Vath gave the SL63 AMG’s sport steering wheel a leather treatment, while also replacing the speedometer with one that goes all the way up to 224 mph and adding aluminum pedals.
Under the hood of the SL63 AMG, Vath worked with a reprogrammed 5.5-liter V-8 Biturbo engine that shot the output of the sports car up to 780 horsepower and 738 pound-feet of torque, a staggering increase from the standard model’s 537-horsepower and 590 pound-feet figures.
