German tuner Wheelsandmore has upgraded the luxury hot hatch with 22-inch wheels, low suspension, and a whopping 810 PS under the hood.
The stock GT 63 S produces 639 PS (630 horsepower, or 470 kilowatts), as well as up to 900 Nm (664 pound-feet) of torque. The Stage 3 upgrade kit takes it all the way to the abovementioned 810 PS (800 hp, or 596 kW). The torque simultaneously rises to 1,030 Nm (760 kW). The scope of required changes includes new exhaust, turbochargers, a catalytic unit, and an ECU remap. You can get it for €19,244.
The Stage 2 kit will set you back €12,605 and still deliver an impressive 750 PS (740 hp, or 552 kW) along with 1,010 Nm (745 lb-ft) of maximum torque. It only includes the ECU remap and the exhaust system. The Stage I package costs a mere €2,160 and yields 700 PS (690 hp, or 515 kW) with 975 Nm (720 lb-ft) of torque.
The lower ride height and the 22-inch wheels are both paid options. No acceleration numbers are provided.
A couple months ago, Wheelsandmore tuned the Mercedes-AMG GT R Roadster (see the video) up to 750 PS (740 hp, or 552 kW).
