The tuners at Rex Accelero came up with this widebody kit when attempting to answer the question of what an SLK 55 AMG Black Series modeled after the SL 65 AMG could look like. They came up with this look which was done by moving out the front and rear fenders by about 2.5 inches. Doing this allowed for the aerodynamic parts to be placed in such a way as to give the car room to be used as a track day device.
A carbon fiber lip plus a rear diffuser will be installed in the final production models. Minimum weight and strength will be ensured by using a vacuum-bag construction. Thus a 50:50 weight distribution can be achieved. Some aspects are still being tweaked ahead of the opening of the pre-order book in September.
This prototype also has oversized tyres, H&R springs, and a standard engine. Although not the 400hp unit from the limited SLK 55 AMG Black Series, it is the same 5.4-litre V8 worth 367hp (270kW) but the California-based tuner has plans to introduce it to a supercharger with the goal of approaching 500hp (368kW). Such a thing is possible; the legendary E 55 AMG had the exact same engine, also with a supercharger and it made 476hp (350kW).
