Every once in a while I like to tweak the physics on cars to have them drive in a way I feel is more realistic, or can be better used to improving my driving. One car I most enjoy driving is a small open wheel car, the formula ford. It is very well done, but I feel there are some areas that could be improved upon. It does have a fair balance, but I feel it could use a little more lift off oversteer. I can adjust the weight balance from 56% rear bias to 58% and it has the amount of lift off oversteer (trailing throttle oversteer, tto)that I am looking for, but there are a few other things I would like to be able to adjust if possible. I feel the rear end does not slide easily enough on heavy throttle. Yes it is a low power car but I would prefer to have less longitudinal grip and have it bring the back end out not just from weight transferring forward but also from too much throttle if the car is already using considerable amount of lateral grip from turning hard. Now when placing more mass toward the rear it also does create more (tto), but then does has even more longitudinal grip on the rear tires when accelerating.
Is there a way to increase or decrease lateral grip and longitudinal grip independently?
Can I adjust the inertia from front to rear independently? Or does anyone know what each number down in blue correlates to?
Can I adjust the grip for the front tires and rear independently?
How could I possibly adjust the grip of the tires vs the slip angle they are at? To be able to make a tire more or less progressive in nature.
Here are some of the settings under "general" in the hdc file.
Thanks,
