Of course a certain amount of sidewall flex is needed - but the question is HOW MUCH? There is an optimum slip angle for max grip which depends on ALOT of things. The type of tires you're running (slicks, r-comps, streets have VERY different optimum slip angles). Also your alignment, weight, suspension, geometry will all matter. Just because you threw out a race car example doesn't make much of a point.

I have first-hand clinical results - running 18's versus 19's back to the back on the same car, same day with same alignment and same rubber I was able to shave off almost 4 seconds at road atlanta - thats what I have to report from experience from MY car - I don't speak for all.
