2009 Mercedes-Benz C 63 AMG tuned by RENNtech
The 2009 Mercedes-Benz C63 AMG is designed to compete against the famous BMW M3 (E92) and Audi RS 4 performance sedan and station wagon, so it is understandable that the car is fast, to say the least.
However, guys from RENNtech apparently decided that they can make the German beast even faster helping it to decisively crush the competition.

The American tuner RENNtech revealed its tuning program for the Mercedes-Benz C63 AMG almost simultaneously with the German-made Brabus B63 S.
Like it is always the case with RENNtech’s tuning program, this package is mostly about the vehicle’s performance.
Although the C63 AMG is quite a hell on wheels even in its original form, the have managed to squeeze 20 per cent more power output from the car’s standard 6.2-liter AMG engine, getting 548hp and 785Nm (510lb-ft) of torque.
This was done by replacing the original exhaust with RENNtech’s own sporting stainless-steel long-tube headers, track-oriented pipes and mufflers. A reprogrammed ECU also pumped some more power under the vehicle’s hood.
By the way, when compared to the aforementioned tuning program from Brabus, the American version of the car looks much tougher with its engine producing 18hp more power and 68Nm (31lb-ft) more torque. And the original C63 AMG looks like a complete pussy with its 457 hp and 443 lb-ft (600 Nm) of torque.
The Mercedes-Benz C63 AMG has also received a set of new adjustable dampers with adjustable camber settings, a set of heavy-duty performance brakes with 15.2 two-piece rotors and RENNtech calipers, as well as a pair of brake ducts made of carbon fiber to help keeping those brakes cool and make them last longer.
