 Keeping the front of the car stable is crucial to the aerodynamic efficiency of the car because changes in ride height - caused by bumps on the road or changes in downforce levels due to speed - can alter the way that air passes over the front wing of the car and therefore the rest of the car's aerodynamic efficiency also suffers.The Tuned mass damper in the Renault R26 was invented by Renault engineer Rob Marshall.The mass damper itself was a cylinder, standing upright, with the mechanical components inside.
