Wheelsandmore offers numerous updates for the Mercedes SLS AMG Coupe, but until now, no updates have been offered for the roadster versions. We said “until now” because today the tuner has announced a brand-new upgrade kit for the SLS Roadster. Customers can choose between two different stage upgrades, with the most powerful one delivering up to 704 horsepower.

In stage II the tuner will install a new exhaust system with sport catalysts and a flap-controlled exhaust. These updates, combined with a software remapping and special sport air filters, will increase the engine's output up from the standard 563 horsepower up to 635 horsepower and 516 pound-feet of torque.

In stage III, Wheelsandmore opted to supercharge the V-8 engine. The end result is a stout 704 horsepower and 630 pound-feet of torque. These updates will significantly improve the car's performance numbers, as it will then sprint from 0 to 100 km/h (62 mph) in just 3.6 seconds and its top speed has been increased to 330 km/h (205 mph).

Along with the engine upgrades, Wheelsandmore is also offering a set of 6Sporz forged wheels, ultra-lightweight aluminum coilover suspension system and LCS coilover suspension with a lift-up function that can raise the car's ride by 40 millimeters (1.5 inches).
