The physics question though is still open. Is dry braking distance a direct indicator of launch prowess? I find it very odd that an extensive google search has as of yet, turned up nothing on this topic. It seems logically so straightforward to me... I guess I could explore whether any research looks at the affect of sidewall flex on braking distance. Thanks for the research lead!
in theory a 35 sidewall would launch better but you have to consider the treadwear rating as well. a 35 sidewall tire that has a 400 rating will spin all day over a 30 tire that has a 100 rating. the higher the # the harder the tire and thus less flex.
as for stopping distance its hard to say because g force lifts the rear and larger front calipers do the braking. it has more to do with the ability to keep the grip and not slide and thats not tested for braking much
