The performance kit that consists of newly calibrated engine electronics with special mapping for ignition and injection, and a high-performance, titanium exhaust system with four tail pipes that’s 40 percent lighter than the factory unit, bumps maximum output from 571HP (563 bhp) to 611HP (600 bhp).
Additional hardware modifications include an adjustable sport suspension from Bilstein that lowers the ride height by up to 40 mm (1.6-inches) at the touch of a button while the driver can also choose between damper settings that offer a more comfortable or sportier ride than the production car.
As an option, Brabus offers a Front Lift System that can raise the front end of the SLS AMG roadster by 50 millimeters (2.0-inches) by pushing a button on the center console in order to navigate over speed bumps or parking garage ramps. The system works at speeds of up to 30km/h (19mph), at which point it reverts to its original position.
The car also rides on more aggressive rubber - 275/30 ZR 20 at the front and 295/25 ZR 21 at the rear - mounted on 21 inch wheels on the front axle and 22 inch in the rear.
In appearance, the SLS AMG Roadster gains a modified version of the carbon-fibre aero-kit that Brabus has previously developed for the gullwing-door coupe. It includes a front spoiler, covers for the upper air-ducts, side skirts with illuminated Brabus logos, side air-vent trim, gas tank cap, a new rear bumper with side air vents and a diffuser, plus a discreet boot lid spoiler.
Brabus says that customers can order all the aero components in a high-gloss finish, a matte finish or in any color they want.
The final touch is the reworked interior sporting a different speedometer with a 400-km/h (250-mph) dial, stainless-steel scuff plates with backlit BRABUS logo, matte-anodized pedals and custom upholstery.
