Ok guys, your not going to believe this so just try it. Put it on any car with any physics and any steering lock. I hit physics gold in a way you have to feel to believe. I have officially made rfactor a 3d tire model now. Their was a problem with the spring rate value of the tires causing them to not deform enough. PROBLEM SOLVED IS ALL I HAVE TO SAY. I had done like everyone else, since a tires spring rate is non linear i input the spring rate of the tire at pressure assuming that meant at the right tire psi the tire would contribute the right amount of spring rate knowing that uninflated the tire had MUCH less stiffness than that. What i didnt realise is rfactor scales things up for you automatically, so when it says to input the uninflated spring rate it means it. So now i've got correct uninflated spring rates and OMG what a difference it makes when the tire actually flexes like it should. Try for yourself you'll see what i mean. I recommend a REALFeel max force (ctrl 7 and 9) of 2500 to 3000 and a damper of 11500.
