I did that using an fz50. all i did was make the rear of the car really soft, (all the suspension adjustments for the rear all the way to left) I then raised the ride height of the rear up so the car sits fairly level. Then add knobbly tyres on the back and put the tyre pressure as high as it will go, set the brake balance nearly all the way to the rear wheels (not all the way or they will just spin in every corner) Its not perfect, there will be a lot of corners where they will all go hideously out of control but sometimes they drift very nicely! Here is a screenshot of what happened at blackwood with a few fz50's, and the setup in anyone fancies tryin it with AI cars (i tried to actually drive on this setup myself and found it impossible!)
When I tried setups posted here there is one general mistake - they are not causing oversteer and focus on rear-end braking, drifting is not ass-dragging.
in previous ai ver they could easily drift 80% of track corners with proper set - now its a bit tricky but still works.
I tried to make very unbalanced set but still controllable.
The key seems to be toe in (max positive on front, max negative on rear), then tire pressure (min in rear) and lastly camber to cause maximum oversteer.
My favorite is fz5 because it has most weight on rear tires and it tends to pull rear out of corner, but for some reason rb4 (rwd spec) seems to do best drifts under AI controll
i made a very fast setup... you have to put your AI drivers use your setups.... The setup is for XRG.... :S I'm a demo racer....
AI cars only can drift when they brakes...
