Getting back to the new improvements, in the Mercury R we find a floorplate which is raised by 7 mm compared to the S version. The modification, implemented to prevent the fastening bolts from touching the asphalt and wearing out, has also allowed us to align the fastening screws to the chassis pipe in their lower mounting point. The floor plate fastening supports have decreased in this section, so as to develop less heat to the chassis during the welding phase. In addition to the fastening and position, the floor plate presents an important change of shape. Its perimeter, now, copies that of the tubes of the front part of the chassis, up to the Cs, with the aim of closing any space and improving the aerodynamics by optimizing the air flow at higher speeds.
