The purpose of this page is to discuss the implications of driver dimensions and help in selecting the drivers for MS16.
Driver Dimensions
Waist-to-Head
This dimension is significant because an increase in waist to head height would mean an increase in canopy height, and as an increase in frontal area (and therefore drag force).
based off of these rough calculations,
A four-inch increase in waist-to-head height (going from 5’8” to 6', for example) will result in approximately a 5% increase in drag force. This will be more noticeable if we decrease the overall width of the car.
Waist-to-feet
The longer the waist-to-foot distance, the longer (or taller) the occupant cell of the chassis will have to be. Not accounting extra supports this would entail, it would cost about 700g per 10cm of length.
Shoulder Width
The wider the shoulders, the wider the occupant cell, the more material, and the wider the car. Egress will also be more difficult and more thought will have to go into designing it.
