FAB Design Mercedes SLS Gullstream – A Look Back

Quite possibly the most radically built Mercedes SLS  to date, FAB Design’s widebody SLS tuning program, dubbed the Gullstream, remains at the top of our list. Originally revealed more than a year ago, I recently saw one of these beauties while on a family vacation at our hotel and had to give you a second look.

Even better looking in person, the FAB Design SLS Gullstream is a widebody kit that features an all new front bumper, fenders, side skirts, rear quarter panels, rear bumper and rear diffuser. A lip spoiler made of carbon fiber is probably the most subtle of all the upgrades while the roof receives a non-functional air scoop.

For wheels, the SLS AMG runs a staggered 10-inch and 12-inch wide setup of three-piece Evolution wheels that feature a concave design. Suspension duties are handled with Koni’s coilovers that can also be found on the SLS GT3 race car, giving the car that ‘stance’ look. FAB has also designed their own quad-tipped exhaust system for the SLS AMG.

Overall power gains goes from 563-hp to 607-hp.
