Mid-O is a lot like VIR: lots of sudden directional changes...coupled with lots of vertical jolts. So, to cope with the former, you need stiff bars and shocks and soft springs. To compensate for the latter (and for the vertical motion), you need to jack up the suspension and use more wing to keep the car from flying off the road. With any of the earlier Mid-O's, the vicious bumps would send anything lighter than a Bentley Continental soaring into the air, but Zwiss' tamed version is much easier on the suspension and the virtual pilot's derriere. Ten-lap race setup.
