Back in 2011 Senner Tuning announced an upgrade package for the Mercedes SLS AMG Coupe version. Today, the same package has been extended to the roadster version . Just like with the coupe , the roadster version receives an extra 35 horsepower under the hood and new wheels, combined with an upgraded suspension system.
Senner Tuning added a new exhaust system made in high-grade steel and a new set of high-performance air filters to help boost its output beyond the standard 571 horsepower and 650 Nm (479 pound-feet) of torque. The end result is an SLS Roadster that delivers a total of 606 horsepower and a peak torque of 508 pound-feet. AS standard, the SLS AMG hits 100 km/h (62 mph) in just 3.8 seconds and a top speed of 197 mph. This package likely drops its acceleration time down to around 3.7 seconds and it may allow the SLS AMG to tickle the 200-mph mark.
Senner also installed new wheels, sized 9-by-20 inches with 255/30R20 tires up front and 11.5-by-21 inches with 295/25R21 Hankook S1 Evo-tires for the rear. The wheels are painted in titanium gray and are combined with a special coil-over suspension system made by KW Automotive.

One does not get to see it too often on German streets, but whenever goose flesh in every car enthusiast. Of course, the Mercedes-Benz SLS63 AMG – classical coupe or open roadster – is at the center of attention here. With it, the designers of AMG scored an absolute big hit as sales figures have impressively confirmed.
The company Senner Tuning from Ingelheim near Mainz did not shy away from assembling a small but nice tuning programme for the sports car that has already now, been enthroned as an icon. There is thus henceforth a special coil-over suspension system of variation 3 from KW Automotive for the SLS, which is adjustable in its compression and rebound stage and also has an aluminium Senner replaces the AMG front rims with a set of Schmidt Gotham-aluminium in titanium gray in the dimension 9x20 inches with 255/30R20 and in the rear in 11.5x21 inches with 295/25R21 Hankook S1 Evo-tires.
In this series, the SLS develops a performance of 571 Horse Power (420 kW) and a maximum torque of 650 Nm. Senner boosts the power of the AMG top model by 35 Horse Power (26 kW) and the maximum torque by 40 Nm through core area adaptation and a precise adaptation to the new exhaust system and the installation of a set of high-performance air filters. The new exhaust system is of course, made of the most sophisticated high grade steel and fitted with a valve control system including a back pressure monitored control system for individual sound volume adaptation with four different modes.
