The tuners from FAB Design have applied their individuality formula on the Mercedes SLS AMG. 
Starting with the front it is impossible not to notice the large air intakes placed under the headlights, with vertically positioned LEDs and the new spoiler lip. Also part of the FAB Design Mercedes SLS AMG conversion are the new carbon fiber side skirts, the new rear spoiler plus the 3-part, 20 inch Evoline wheels.
There is also a roof air-scoop and a massive exhaust system at the back, while in terms of performance the FAB Design Mercedes SLS AMG now boosts 611 PS instead of 571 PS like the stock model.
Completing the FAB Design Mercedes SLS AMG enhancement program is the new sports suspension, while pricing for the newly added components was not announced. 
FAB Design press release :
The Swiss tuner FAB-Design has taken on the new AMG Mercedes SLS to make it that much more individual. True to the company‘s philosophy of creating something even more individual from a noble factory vehicle, a more accentuated version of the wing-door car has been produced. Especially the aerodynamics benefited from the high class fine tuning. To do this the developers from Mellingen developed and mounted a sporty front spoiler lip with vertically mounted daylight driving lights along with a rear apron with integrated diffuser in a similar design to the front element. An equally output boosting rear spoiler that was specially constructed to perfectly harmonise with the factory mounted extendable counterpart crowns it all.
The optical and aerodynamic cherry on the SLS cake are the side skirts made of visible carbon fiber. A further highlight on the retro-sportscar are the 3-part 20 inch „Evoline“ complete wheels.
The classic hole-design thus harmonises perfectly with the equally classic sportscar silhouette of the FAB SLS. In addition a fitting sports suspension set was mounted that equally satisfies the requirement
for both comfort and sport. At the rear of the vehicle a FAB stainless steel sports exhaust with four oval endpipes lets the exhaust gases go sonorously free. Integrated valve steering gives the driver the possibility – according to the occasion – of choosing between a sonorous and a discrete sound.
The FAB developers also worked on the improving the performance and thereby achieved an every day capability of 611 PS – instead of the normal 571 PS of factory vehicles.
