There's nothing wrong with using pre-existing setups. Remember that when you're a rookie who's never tuned your car before, having all those adjustments suddenly becoming important can seem daunting, and even a turn-off. You can't expect newbies to just automatically be interested in understanding caster, camber, toe, roll center, shock setup, spring rates, weight ballasting, etc., when all they really want to do is hit the track and drive. That's like expecting a ten-year-old to automatically be interested in school. (Not accusing anyone of being immature, just an analogy!) Yes, some individuals, when they are first starting out, are interested in the technical side of car setup, but most are not. Everyone learns at their own pace. And that learning would be a lot more difficult if successful setups were not available.
