German tuner Mariani has rolled out a host of modifications for the Mercedes-AMG GT 63 S 4-Door and while the tweaks are somewhat minimal compared to some other tuners, they do promise to make the super sedan that little bit more special.
Kicking things off is a new set of wheels offered in 21-inch and 22-inch forms. Mariani notes that the 21-inch wheels are 11-inch wide at the front and 12.5-inch at the rear and wrapped in sticky tires measuring 325 mm out back. That’s probably overkill for a car like this but the wide wheels and tires help to perfectly fill out the arches.

With the wheels sorted, Mariani has dropped the ride height by as much as 55 mm (2.1 inches) while retaining the car’s original active dampers and E-Active Body Control system. A slightly more aggressive diffuser has also been developed for the GT 63 S 4-Door as has a new exhaust and tailpipes. This exhaust is made from high-quality stainless steel and includes an adjustable flap to allow owners the ability to customize just how loud it is. Importantly for German customers, the exhaust is also TÜV approved.
The performance of the Mercedes-AMG GT 63 S 4-Door has also been boosted. Marini says the 4.0-liter twin-turbocharged V8 is now good for 725 hp and 700 lb-ft (950 Nm) of torque. These are significant gains over the standard GT 63 4-Door rated at 577 hp and 590 lb-ft (800 Nm) while the GT 63 S 4-Door is typically good for 630 hp and 664 lb-ft (900 Nm). However, Mariani’s creation doesn’t pack quite the same punch as the hybrid GT 63 S E-Performance with its 831 hp and 1,033 lb-ft (1,400 Nm) of torque.
