I have a problem with a modded car I'm messing around with. The car behaves fairly predictably and within the performance envelope I wanted it to achieve. But I have found it has a fatal AI flaw. The car can't make high speed weight transistions. When driving it myself, I may find that to complete a quick left/right combo, (like the middle chicane at Birmingham/Barber) I'll have to lift slightly off the throttle. Not always tho..usually when I get the corners driven correctly, the car CAN make the turns. But the AI never feels this problem and will often loose the back end upon exiting the corner. I've tried increasing rear downforce, moving the front/rear weight ratio, messing with setups...nothing seems to completely cure the problem. I have thought, at times, my changes have corrected the problem. But if I leave the AI alone...sooner or later the spin will re-occur and once it starts, the AI seems more prone to repeat it. So what causes a loose condition upon corner exit? I feel it's the weight transition itself, but I 'should' have been able to dial that out. I have even had the downforce configured so that the front feels light almost bouncy with a rear wing providing most of the traction. But it can't seem to keep the back end planted when there is this sudden double direction change. There is even one track with a long downhill corner (VIR's last turn) that causes the same spin. The car is weighted to the inside of the track but as the ai change direction for the last corner back onto the main straight, the weight of the car rolls to the outside and the back end falls away to the outside. These spins are not sudden snap spins but slow PAINFULL affairs. If you were working on setting up a car, what areas would you look at to FIX this condition? dizzy dave

Hi Dave, even though i don't consider myself smart, or being an awfully fast sim-driver for that matter, setting up cars is kind of a hobby. First thing to figure out tho is if it actually is just a setup Problem or a general rF AI issue. But let's assume it's the setup. Try to heaviuly reduce rear-end roll by stiffening the bar and/or the springs. Also, stiffen the outside rear damper in the bump direction and the inside rear one in the rebound direction. shifting some downforce from front to rear may also help, but i think you tried that already. Anyway, that's my take on it. If everything fails, just steal the AI massive amounts of front end grip and see what happens... Cheers! Cris
