Karting isn't a good comparison to full-size "real" cars. Karts have to have chassis flex as they have no suspension. Having a suspension divorces brake mounts from chassis flex, but you still have to deal with bearing clearances and hub/rotor flex. In a street-driven car that does not see a track or Autocross you won't likely see flex inducing any perceptible knock-back.
