[What'saCobra?]

Sounds like kindergarten. Johnny wouldn't share with me...

Every chassis sets-up differently and driver preference, skill and style have a great deal to do with it. And that's for the same equipment, that is... presuming even exactly the same mechanicals, which isn't very likely. Sticktion, draging, limits, concentricity, pick-up preferences and mods, center-lines and lots more affect final settings, when they cannot either be controlled-out of the set-up or ignored due to time or lack of knowledge...

i like things pretty twitchy to keep the tires hot up north, but some prefer more dynamic stability and less throttle over-steer down here in Florida in the summer to reduce tire temps. Now, when we go out with cold tires, in the cold, in a twitchy car, be careful on the first few laps, right? Plenty of dopes have lost it on the warm-up lap; but not me (yet, and close doesn't count). Plenty more lose it in the first corner after the spin for the same reason, forgetting tire condition and how it changes when cold or dirty.

Initial settings are just a recommendation and don't reflect anywhere near the whole story. Given the time it takes to find what's best for me, today, on this track and the seat time it takes to make intelligent choices, i would rather have an experienced professional show me how, on the payroll. That's just me, i guess.

Otherwise, we can get it in a book and experiment.
