Both the Chevrolet Camaro GT4.R and Mercedes-AMG GT4 have been adjusted in the GS class, with the Camaro getting a 20 kg weight break and a 5 kg increase in minimum weight for the Mercedes.
The Mercedes has also received a 2 mm increase in front ride height, a 1-liter increase in fuel capacity and a move to SRO’s 2019 engine Map 5.
