>>28458651>But you just edit some numbers,no you don't, actually. you are adjusting the actual suspension geometry of the simulated vehicle which affects the tire the exact same way it does irl, provided the simulated vehicle and the real vehicle have the same suspension geometry, which i'll admit is often not the case. the numbers you see in some tuning menus are often kind of irrelevant for this reason, what you're actually looking for are measurement proportions, and certain proportions do specific things to the car handling in various situations that are pretty much universal for all 4-wheeled vehicles.
this is why the best alignments are done with a laser machine that can track where the center of the wheels' axis and center of thrust of the car actually is, and even if you have physical alignment tools, adjusting irl cars' alignment is a more analog, involved, and careful process. but you are doing the exact same thing, so you can actually use the sims to plan what you want. hardcore sims like rf or ac really do tell you what you're doing in measurable degrees or inches of adjustment, but it does depend entirely on the author of the content you are playing to have recreated the vehicle correctly.
