To give the SLS an even more muscular appearance the Brabus designers have developed custom-tailored Brabus Widestar components for the rear axle. Like all other body components they are made from extremely light yet very strong carbon fibers identical to the ones used in Formula 1 racing. The add-on parts for the rear fenders and the rear fascia create an even more spectacular look and make room for special wheels that widen the rear track by 20 millimeters for even further improved driving dynamics.
The suspension engineers developed custom-tailored versions of the ultralight Brabus Monoblock F Platinum Edition forged wheels in sizes 9.5Jx20 in front and 11Jx21 on the rear axle for the wide version of the Mercedes-Benz SLS AMG. These wheels are available with a brushed-design or ceramics-polished surface and can also be painted in any desired color. The staggered wheels with 20- and 21-inch diameters on front and rear axles further emphasize the wedge-shaped look of the sports car.
Despite the wheels’ bigger size they deliver a weight reduction of up to 12 percent compared to the SLS production wheels. The reduced unsprung weight further results in even more agile handling. Brabus technology partners Pirelli and Yokohama supply the optimal high-performance tires in sizes 275/30 ZR 20 and 295/25 ZR 21.
The ride-height lowering by up to 30 millimeters (1.2 inches) also plays an important role in the striking appearance of the Brabus-modified SLS. The Brabus suspension is height-adjustable and was developed in cooperation with technology partner Bilstein. At the push of a button its integrated Ride Control function also offers a smoother ride than the production car. From the cockpit the driver can at any time – even while driving – switch between damper settings that offer a more comfortable or a sportier ride than the production car.
The Brabus high-performance exhaust system with four slanted exhaust tips with diameters of 84 millimeters (3.3 inches) is somewhat atypical for traditional tuning. Its sound management, controlled by the driver and activated by a pneumatic flap, includes a ‘coming home’ setting that is quieter than the production exhaust. In ’sport’ mode the 6.3-liter eight-cylinder engine produces an even more powerful exhaust note than with the production exhaust. The Brabus exhaust system is manufactured from extremely lightweight titanium and weighs 12 kilograms (26 lbs.) or 40 percent less than the production exhaust. Another welcome by-product of this exhaust is an increase in power output by 10 hp / 7.4 kW.
