Interesting thread I found on a random forum

was researching random stuff about aero and i stumbled upon this question:

not sure if they were serious or not, but i wanted to share it because i got a pretty good kick out of it

 

giving the car more physical mass gives it more inertia, making it worse for changing direction.

 

exactly, downforce adds downward force onto the tires without adding extra inertia to the car, making it behave like a lightweight car, with extra ”weight” on the tires to add grip. downforce adds ”weight” but not inertia

 

F1 doesn't have "slow" corners thoooooooooooo

when are you pro track makers releasing an (almost) fully inverted tron track that takes advantage of the gravity-defying downforce provided by the FR17/15 on the repository

 

That's where front wings get into the play, rear wing is for downforce whereas front wing is mainly for stability and faster turning in slow corners.

 

Here is something that puzzles me though, why rFactor and BeamNG then have tire physics that revolve around tire looses grip with added weight thought. This came in 0.9 version with improved friction that is in devblog.

While it is true that added inertia negates any gains of added weight, added weight does increase friction, downforce would not work otherwise.

"Now the ultimate grip of the tire is reduced when the tire nodes are loaded heavily"

Is it then only lateral load that is being meant? Or does it mean only really heavy loaded cases like 10 times of usual load?
