Mariani Gives the Mercedes-AMG GT 63 S 4-Door a Juicy Upgrade You Won't Want to Miss!

The German wizards at Mariani have worked their magic on the Mercedes-AMG GT 63 S 4-Door, and let me tell you, the results are jaw-dropping.

First up: those wheels! Mariani is rolling out new wheel sizes—21 and 22 inches to be exact. Now, you might be thinking, "Isn't that a bit much?" Nope, not at all.

These bad boys are 11 inches wide at the front and a whopping 12.5 inches at the back, hugged by 325 mm tires that make the car look like it means business. Seriously, this thing now looks like it's flexing at the gym 24/7!

Let's talk ride height. They've lowered this beauty by 55 mm, and don't worry, they kept the car's original smart tech—active dampers and the E-Active Body Control system—all intact. But wait, there’s more: the car now sports a more assertive diffuser and a brand-new, stainless-steel exhaust. This thing not only looks cool but sounds like a beast. Plus, you get to decide how loud your beast roars with an adjustable flap. And hey, for those in Germany, it’s TÜV approved. Nice!

Now, get this—the performance is off the charts! Mariani's dialed up the 4.0-liter twin-turbo V8 to a staggering 725 hp and 700 lb-ft of torque. That's not just a baby step, that’s a giant leap over the regular GT 63 4-Door and even its already souped-up sibling, the GT 63 S 4-Door. Sure, it’s not as crazy as the hybrid GT 63 S E-Performance, but let’s be real, it’s still enough to make your heart race.
