The Mercedes-AMG GT S is definitely a head-turner, even in stock form. But as everyone knows, there will always be clients looking to make their rides a bit more unique.

Fostla has come up with a few aftermarket upgrades that cost € 28,000 (US$ 32,703) in Germany. First, there’s the power upgrade, which bumps the output from the original 510 PS and 650 Nm of torque, to 613 PS and 768 Nm of torque.


This number was achieved with some ECU tuning, plus the addition of a BMC high performance air filter and Frequency Intelligent-exhaust-downpipes, according to the tuner. Fostla doesn’t say how quick the Mercedes-AMG GT S is with their upgrades, but seen as how the stock model takes only 3.8 sec to reach 100 km/h, and maxes out at 310 km/h, this car should build on that performance quite nicely.

Next comes the carbon fiber aerodynamic kit, consisting of a front splitter, intake add-ons, sidebars, rear diffuser and adjustable rear wing. These are being complemented by a KW lowering suspension, and H&R spacers for the wheels.

Finally, Fostla wrapped the entire car in vinyl, featuring a two-tone matte silver and red pattern, along with the PP-Performance logo on the windscreen and the Fostla lettering on the sides.
