The second generation of CLS-Class has received an upgrade by Bavaria-based tuner VÄTH. The Germans installed an improved performance, and exterior and interior trim on the Mercedes-Benz CLS 63 AMG V8 Biturbo.
A V63RS tuning kit features individually fine-tuned engine electronics, which increases the the capacity to 5.461cm³ and the maximum output is 660hp and 960Nm.

The kit price, including optimized charge air cooler system and sports exhaust system consisting of stainless steel catalysts, middle and tail muffler systems costs € 12,800.
The suspension in CLS 63 AMG by VÄTH features the front axle lowering springs of 20 to 40mm plus rear axle electronic adjustment, it will cost you € 980. In order to improve overall performance it also makes sense to optimize the brakes which will cost € 590 with flexible steel brake lines, Technical Supervision certificate and Castrol SRF racing brake fluid included. Another € 6,337.88 you would have to pay due to the forged three-piece 9×20 inch wheels with 265/30ZR20 tires for the front axle or 10.5×20 inch with 305/25ZR20 tires for the rear axle.
On the outside they fitted an airflow front spoiler (€ 1,490), a trunk-lip spoiler (€ 1,480) and a rear diffuser with fins and underfloor extension (€ 1,490).
Väth provided a car with a sports steering wheel in leather/leather design, also available with carbon or finewood applications upon request. For another € 1,450 the tachometer scale can be extended up to 360km/h. And last but not least, for € 3,300 you can choose improved interior design in classy black carbon.
