One solution put forward was ride height adjustment made during the race. Since the ban on active technologies in the nineties, the rules are clear, there can be no adjustment of the cars suspension while it is moving, equally parc ferme rules prevent any changes between qualifying and the race. But teams could have a mechanic adjust the ride height during the pitstops.This would be legal and feasible, as the pushrods or torsion bar mounting could be fitted with a quick adjustment mechanism. Even within a sub 3 second pitstop, this could be completed accurately. But as the car will start the race with qualifying (low fuel) ride height settings, this could not be adjusted until the first pitstop, thus the opening stint would be compromised by the wring ride height. Of course the balance of the race could then follow the ride height with the decreasing fuel load, but adjusting at the second and subsequent stops.
How could this be done?
Teams generally adjust ride height with shims fitted to the pushrods. The pushrod is split between the main shaft and the metal end fitting, by loosening the bolts that tie them together a shim can be added into the gap. Thicker shims mean more ride height and the shims need to be added to each of the four pushrods (two front two rear) to gain a balanced ride height. Adjusting via this method is impractical during a rapid pit stop. The pushrods could have a threaded adjuster as used on the front wing flap, a turn of the adjuster drops ride height by a fixed amount, this would be quicker to adjust, but still all four relatively in accessible (during a hectic pitstop at least ) would be difficult.
More likely would be to rotate the fixed ends of the torsion bar springs, by fitting the torsion bars on each axle to a common mechanism, they could be quickly adjusted by a single adjuster (two in total for the car) accessible through the top of the chassis or gearbox. Although the latter would be still hard to access shrouded by the rear wheels and rear wing, plus the associated wheel change and jack mechanics.
