I've been doing some races on VIR and the AI has a habit of flipping in the first sector coming out of the tight right hander into the chicane before the bridge. They hit the inside or outside curb and spin. Are there any ways to tweak the racing lines or AI to get them to chill out here and stop flipping and spinning!

You'll have to be specific about which cars are doing this. It isn't all of them.

I've definitely seen this behavior at VIR. With the recently released GTPC mod the AI prototype cars will indeed spin or completely flip over on a relatively consistent basis. With the AJRs and one of the Caterham models I find that AI the cars won't necessarily flip or spin but they will bounce their inside wheels so high in the air that they have to slow way down to recover. This obviously makes them uncompetitive if not outright obstacles you need to avoid.
I seem to recall the Boxer Cup cars would sometimes flip as they came out of the right-hander in the section before the bridge. It stuck in my mind because such AI behaviour is rare in Automobilista.
It is a real shame as the track is a blast with the cars!

The mod needs to be adjusted so the AI physics handle the curbs better - since AI suspension physics are simplified vs the player, hitting high curbs with a lateral load may cause the AI to tip off if their suspension values are not appropriate.
Look out for the following values in the GENERAL section vehice´s HDV, softerning them might reduce tipping:
AIEvenSuspension=1.0
AISpringRate=1
AIDamperSlow=0.8
AIDamperFast=0.8
A couple of "hack" values that can possibly fix the issue, also in the HDV general section:
AITorqueStab=(1.0,1.0,1.0)
The 3rd value adds a torque adjustment on the roll axis of the AI cars, setting that to 1.25or so may help keep them stable.
Finally the simplest solution and possibly one with least side effects is to set the AI center of gravity height to 10% or so lower than the player, ex:
CGHeight=0.372
CGHeightAI=0.342

Renato,
Any chance that this could be pushed as a hotfix on steam so that it fixes this issue for others. I've yet to try it but if it works it would be a good fix.

If you could specify what cars from the game youre finding that problem with I could have a look, I was under the impression the issue was with mod cars and in those cases it would depend on the author.
I've not been using mods. But the Metalmoro's at VIR tend to flip a lot and I've noticed that the V8's and even Mitusbisi's flip in the first chicane at Adelaide
Renato,
Quick question, lowering the centre of gravity will make the cars handle better? I'm used to adjusting downforce levels in the HDV files, along with a few other parameters in the tbc and engine files, I never really knew what the CG entry was, if that's the case that's brilliant for what I'm working on now!

Sorry for reviving this, But with the EEC Endurance Mod there isn't a CGHeightAI. What do i have to do?
