Cutting off the roof, might significantly increase the aerodynamic drag coeficient, which dependent upon the relative magnitude of effects (i.e. drag force versus mass-inertia and vector component of weight parallel to hill gradients), resulting in a possible fuel-consumption increase!marsh-the-great wrote:helps with power to weight ratioHloni wrote:Lighter car = less fuel usedmarsh-the-great wrote:guys here just cut the roof of completley
Besides that, unless one takes measures to strengthen the car to restore its stiffness and provide a roll cage (i.e. add back additional weight), after cutting off the roof, the vehicle is likely to be unsafe!
