Our test car was also equipped with 18" 5-spoke AMG alloy wheels - 225/40 front tyres and 245/35 rear tyres including sports suspension (£1,200 option). The sports suspension option offers a firmer suspension setup and damping settings. With the sports suspension fitted, the body is lowered by 10 mm at the front and the rear and total spring travel at both axles is shortened by 10 mm compared to the standard chassis, while the spring rates increase by as much as 10 per cent. The result is minimal body roll and exceptionally high levels of grip.
With the 18" AMG wheels and lowered suspension you certainly feel in tune with the road surface but the ride remains supple. Mercedes-Benz have made an excellent job of filtering out unwanted vibrations including scuttle shake which is indicative of most convertibles, roof up or down.
