RENNtech tunes the Mercedes-Benz C63 AMGEnlarge Photo
Rated at 548hp (408kW) and 510lb-ft (785Nm) of torque, the 6.2L V8 in the RENNtech C63 AMG tops the factory-tuned model by about 20%, or 97hp (70kW). The power gains come from an all-new exhaust system, including stainless-steel long-tube headers, track-oriented pipes and mufflers plus a reworked ECU. To contain all the extra power RENNtech also upgrades the suspension and fits a new brake package.
Fully adjustable dampers with adjustable camber settings mean the vehicle really can be tuned for the track, or multiple tracks, giving this car a sporting potential many overpowered tuner-cars lack. The upgraded brake package fits right in line with the track-day aspirations of the rest of the car, offering tremendous brake torque and fade resistance with 15.2" two-piece rotors and custom RENNtech calipers. Stainless-steel braided lines ensure solid pedal feel while a pair of carbon-fiber brake ducts help improve ventilation to keep braking consistent lap after lap.
