The Mercedes-Benz SLR McLaren brakes have been strongly criticized by such review sources as Top Gear due to lacking modulation and having an on-off operation. This is due to road cars not regularly reaching normal operating temperature for ceramic discs in stop-go traffic conditions. Mercedes-Benz SLR McLaren (15 in 722 edition), when demanded via the driver’s switch, the elevation can be increased to 30 degrees (35 in 722 version) for increased rear downforce, at the cost of increased steady state drag, also when the driver applies the brakes the spoiler raises.
