Even though Mercedes has built a road-legal AMG GT3, tuners have been there to make some changes on it and add some better looks and power. Meet the IMSA Mercedes AMG GT RXR One. Don’t be fooled with the massive aero parts or the wide arches on IMSA Mercedes AMG GT RXR One. The car is still a sweet grand tourer at heart. It just happens to look like the bastard child of Godzilla and Predator. Mind you, IMSA Mercedes AMG GT RXR does have some motorsport skills. It’s not all show. Stating with a AMG GT S, the tuner has replaced major body parts with lightweight carbon fiber pieces. So you have the weight advantage. Then there is the race car-grade aerokit, complementing the adjustable race suspension, new axle parts and the forged aluminium wheels. The V8 engine is also improved with tweaked turbochargers and a new cooling system. Las but not least, you get track-ready Pirelli Pzero Trofeo R tires.
