These things change significantly during a race, with even more changes coming from the changes that happen throughout a race's distance.
Some of these changes are both ambient and track interface temperatures, tire sidewall temperatures, which effect sidewall stiffness. Tire contact surface, both mechanically and dynamically (again, due primarily to temperature and near the end of their "stint", changes in hysteresis (which in this case is the tires ability to change as little as possible as the sidewall has become cycled enough for it to change its "spring rate", and as importantly, its "lag time" in doing the same things over and over (which is really the definition of "hysteresis" in this case.
Understanding what your tires are doing, even for short duration events, is a very valuable input as you continue to learn about your car.

How does one quantify maximum tractive effort and relate it to individual seat of your pants driving style? Are you trying to acheive the most longevity for your equipment, quickest lap times....? What specific means are you trying to achieve?

Anyone want to take some time and think about how we might make it what it should be? A literal repository of the knowledge and experiences of the many RacersWeb.com fellowship to hopefully enrich and provide some guidance to those who are still climbing the ladder.

Then it shouldn't be ask a pro specifically, this only creates two type of questions which will generally be based on the person themselves or the style of racing they participate in. Either they will be questions that require empirical data (setup questions, logistics, preference, what happens if such should occur.....what's your favorite color/food/brand of skivies....) and those with intangible answers (how you
feel the car.)
To be honest, how much does the pro driver really know about the prep, transport or setup of
their equipment now a days? If we're talking old school guys who came up through the ranks wrenching on their own rides they'd have a better understanding. The bred to race type though? Or maybe my perception is out of wack....
If you're trying to pull from the knowledge of our members I think we need to utilize some of the tools we currently have available that aren't being relised or used to their potential. We have forums dedicated to prep, setup, materials etc that lay dormant. Lets use these as our baselines for building an encyclopedia of that knowledge our members possess. Things such as terminology, understanding suspension (geometry, kinematics, application, setup) aero, track prep, tools/equipment no one should be without.
Then when it comes time to ask a question of value you know specifically what you're looking for; such as how do you address the bump steer on x,y,z track or corner, or how do you balance the compliance of your suspension given this track condition, or how do I tune out the 'ripples' in this section of track so Iam not ice skating....
Getting light headed.......need to step of my soap box for a while
