the ideal suspension….?

hy…. since in racing often very deep, fast and also apparently well “legged” cars (porsche 11er) go to the start, has opened up a question with me. can a super driver (e.g. a porsche 911 turbo) be prevented, e.g. over the nordschleife hammers also really with hard limiters at the inspring? I always thought that this is the absolute supergau and in this moment the vehicle is “unberechenbar”.how can one realize in racing the springway limitation effectively, o Is it necessary to use these pu zasatzfeder to increase the spring rate or to progressively apply this? how much one-way travel must still be guaranteed, so that you don’t have a part of German roads during a sporty ride? (ideal example would be the Nordschleife again, which is very similar to the road?) I would be very happy about expert answers. gruß micha
