• Wheelsandmore Adds Some Serious Pop to the Mercedes SLS Roadster

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).

Press Release

Depending the delivery date of his Mercedes SLS AMG Roadster the proud owner could extensively approve the standard performance of this beauty. Now, that the sun moves again about to the Tropic of Capricorn in Europe, most Roadsters will disappear in garages and the inclined owner of a SLS got a lot of time to think about improving the performance. In that case Wheelsandmore offers help by introducing the new performance upgrades up to 704hp.

Stage II: To the already proven software remapping, a stainless steel exhaust system with sport catalysts and a flap-controlled exhaust (maintaining the standard tailpipes) was adapted, resulting in total 635 hp and 700 nm torque, combined with special sport airfilters.

Stage III: In addition to the performance stage II the naturally-aspirated V8 engine is supercharged with compressors. 704hp and 855nm of torque is the impressive final result of dyno testing. Then the roadster passes the 0-100 km/h sprint in breathtaking 3.6 seconds and the top speed is electronically limited at maximum 330 km/h.

Befitting the noble tuner upgraded the wheels of the Mercedes SLS AMG Roadster with handmade forged wheels of the type 6Sporz ², turning on the front axle sizing 9,0 x21" with 245/30/21 tires and on the rear axle in handsome 11,5 x21" with 305/25/21 tires. An ultra-lightweight aluminum coilover suspension, variable in compression and rebound, provides further improved sports character. Optionally Wheelsandmore provides a LCS coilover suspension with a lift-up function, which allows raising the front and rear axles around 40mm by pressing the remote control button.

I like the Mercedes SLS Roadster since it looks like a convertible with its no roof appearance. The engine looks upgraded and nice. I just hope that the standard performance is certainly improved.
