The Mercedes C63 AMG Coupe is one of those cars that really doesn’t need a tuning upgrade, but if there’s a company that’s willing to make a program for it, then we’re all for it. Domanig doesn’t make our pages often, but with their new program for the C63 AMG, it definitely deserves to be talked about.For starters, the Mercedes sports coupe was given a couple of aerodynamic parts, including a a new carbon fiber front spoiler, a blacked out roof, and a new rear diffuser. The finishing touch is a new set of special edition 20" forged DOM03 type wheels with a star in the body color and outer rims in black high-gloss polished stainless steel, wrapped around Dunlop Sport Maxx GT tires. The C63 AMG Coupe also gets a new KW suspension system and interior trims and accents.Under the hood of the Mercedes, Domanig wasted little time tweaking the car’s 6.2-liter V8 engine that produces 487 horsepower. Thanks to their magic hands, Domanig was able to improve the car’s output to 525 horsepower and increase the top speed to 186 mph.
